Calculate the percent increase of mobile device sales from 1998 to 2007. Each mobile device sold in 2007 contained an average of 0.03 gram of gold. Calculate the number of grams of gold that were used in the production of the mobile devices sold in 2007. Assume that the average mass of each mobile device was 0.1 kilogram. The United States Environmental Protection Agency estimates that about 10 percent of the mobile devices sold in 2007 were recycled. Calculate the mass (in kilograms) of the mobile devices sold in 2007 that were not recycled. Discarded mobile devices become part of the electronic waste stream (e-waste). Mercury is often present in e-waste. Identify one negative human health effect, other than death, associated with exposure to mercury.

Answers

Answer 1

Based on the number of phones sold in 1998 and 2007, the percent increase is 500%.

The number of grams of gold used in producing the mobile devices sold in 2007 was5,400 kilograms of gold.

The mass of sold phones that were not recycled is 16,200,000 kg.

What was the percentage increase in phones sold?

= (180 million - 30 million)  / 30 million x 100%

= 500%

What was the mass of gold in phones sold in 2007?

= 0.03 x 180 million

= 5,400,000 grams or

= 5,400 kg of gold

What was the mass of mobile devices that weren't recycled?

= 0.1 kg x 180 million x (1 - 10%)

= 16,200,000 kg

What is wholesaler delivers?

A wholesaler's main duty is to improve the efficiency of the supply chain for the gain of producers, distributors, and end consumers. At the same time, wholesalers help distributors manage their assets more efficiently.

Between a manufacturer, who creates a product, and an organization farther down the supply chain, a distributor serves as a link. A value-added reseller, or downstream company, can be either a wholesaler or a retailer.

A distributor is a company that buys non-competing products or product lines and resells them to customers directly. The majority of distributors also provide a range of services, including service, technical support, and warranty protection.

Thus, option C is correct.

5. The sales manager is convinced that a 11% reduction in the selling price, combined with a $68,000 increase in advertising, would increase this year's unit sales by 25%. a. If the sales manager is right, what would be this year's net operating income if his ideas are implemented? b. If the sales manager's ideas are implemented, how much will net operating income increase or decrease over last year?

Answers

Answer:

5(a)  $1,156,000

5(b)  -$104,000

Explanation:

5(a)

The reduced selling price

= [tex]120-13.2[/tex]

= [tex]106.80[/tex]

The revised fixed cost

= [tex]180000+68000[/tex]

= [tex]248000[/tex]

The revised number of sales unit

= [tex]24000\times 125 \ percent[/tex]

= [tex]30000 \ units[/tex]

Now,

The computation of net operating income will be:

Sales

= [tex]30000\times 106.8[/tex]

= [tex]3,204,000[/tex] ($)

Variable costs (less)

= [tex]30000\times 60[/tex]

= [tex]1,800,000[/tex] ($)

Contribution margin

= [tex]Sales-Variable \ cost[/tex]

= [tex]1,404,000[/tex] ($)

Fixed costs (less)

= [tex]248,000[/tex] ($)

Net operating income

= [tex]Contribution \ Margin -Fixed \ cost[/tex]

= [tex]1,156,000[/tex] ($)

5(b)

The net operating will decrease over last year will be:

= [tex]1,156,000-1,260,000[/tex]

= [tex]-104,000[/tex] ($)

The public power company is an example of which market structure?
A. Perfect competition
B. Monopolistic competition
C. Oligopoly
D. Monopoly

Answers

Answer:

D. Monopoly

Explanation:

A monopoly is a market structure which is typically characterized by a single-seller who sells a unique product in the market by dominance. Thus, it is a market structure wherein the seller has no competitor because he is solely responsible for the sale of unique products without close substitutes. Any individual that deals with the sales of unique products in a monopolistic market is generally referred to as a monopolist.

Hence, the public power company is an example of a monopoly because they serve as the only power utility provider to the public.

Additionally, a public power company refers to a company that provides power (electricity) utility to the general public of a society.  

A store advertises new TVs for $100 a month for six $600 in order to
A. encourage customers to buy more than one item
B. make a larger price tag look more manageable
C. make signage more attractive to shoppers
D. significantly reduce the amount of tax taken

Answers

Answer:

B. make a larger price tag look more manageable

Explanation:

A price tag of $600 may see a too high price for many customers. To eliminate the perception of a huge price/expensive TV, the store opts to spread the TV cost over six months. The customer will end up paying $600 for the TV( 6 x $100).

The $600 price tag may discourage some customers, which translates to a loss of sales. $100 for six months is attractive, pocket friendly and may generate many sales to the store.

A consumer has utility function U(x, y) = min{x, y}. She has $150 and the price of x and the price of y are both 1. The consumer is thinking of accepting a job in a different town, in which the price of x is 1 and the price of y is 2. Her income would remain the same. This consumer, who understands compensating and equivalent variation perfectly, is torn. While she is keen on the prospect of a move to the new town, which boasts a fine array of cultural activities for her family, she claims that, purely on the basis of her own preferences, having to move is as bad as a cut in pay of $X. She also claims she wouldn’t mind moving if when she moved she got a raise of $Y. What are the quantities $X and $Y equal to?

Answers

Answer:

The answer is "X=50 and y=75".

Explanation:

X = Variation equivalent  

Y = Variation to compensate  

Pre-movement equation:

[tex]\to x = y = 75 \\\\ \to U= 75[/tex]

The post movement equation:

[tex]\to x = y = 50 \\\\\to U = 50[/tex]

Service decline corresponds to a reduction in the salary of:  

[tex]\to 25 \times 1 + 25 \times 1\\\\\to 25+ 25\\\\ \to \$ 50\ \ \ _{(modify \ \ Equivalent)}[/tex]

Now she wants:

[tex]\to 25 \times 1 + 25 \times 2 \\\\\to 25 + 50 \\\\ \to \$ 75 \ \ \ _{(compensating \ \ variation)}[/tex]

to get [tex]U = 75[/tex] in the new city.

Answers

Answer:

Explanation below

Explanation:

Language Barriers - both language and linguistic abilities can serve as barriers to communications between people. When people communicate using the same language, terminologies used in the message can form as barrier in the communication. It is best to use the language that can be rightly understood by the receiver.  

Psychological Barriers – The psychological mind of the person receiving the message could serve as a barrier to communication. When people experience certain stress and personal issues, it could preoccupy their minds and that may make them not to be receptive to messages as expected. Stress management could help alleviate the challenges around this psychological barrier issues.  

Physiological Barriers simply have to do with the receiver’s physical state. If the person is not hearing well maybe due to background noise, then the entire messages may not be grasped by the receiver. It is best to ensure there are no background noises.

Physical Barriers include the geographical distances between both the sender and the receiver of the message. Modern technologies have been used to reduce the impact of physical barriers.  

Attitudinal Barriers are the behaviors or perceptions that hinder people from communicating effectively. Such barriers can come up as a result of personality conflicts between the people or resistance to change. It would be ideal if both parties that are communicating try to overcome their attitudinal barriers before they can communicate. Better enlightenment can be used here effectively to correct issues.
