1. At best buy they have a 50" TV that sells for $1450 and is on sale for 20% and sales tax is
7.5%. What is the final cost?

Answers

Answer 1
i think it’s 1,247. explanation: take 20% of 1450 and subtract it since it’s on sale, giving you 1160 after subtracting 290. then, take 7.5% of 1160 and add it. 7.5% of 1160 is 87, so if you add 87 to 1160, you get $1,247. hope this helped!

Solve 17 - x = 1 + 3x

Answers

x = 8

We’ll combine like terms by getting all the x terms on the right, all the digits on the left.

16 = 2x
Divide both sides by 2
x = 8

Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

1) Add x to both sides.

[tex]17 = 1 + 3x + x[/tex]

2) Simplify 1 + 3x + x to 1 + 4x.

[tex]17 = 1 + 4x[/tex]

3) Subtract 1 from both sides.

[tex]17 - 1 = 4x[/tex]

4) Simplify 17 - 1 to 16.

[tex]16 = 4x[/tex]

5) Divide both sides by 4.

[tex] \frac{16}{4} = x[/tex]

6) Simplify 16/4 to 4.

[tex]4 = x[/tex]

7) Switch sides.

[tex]x = 4[/tex]

Therefor, the answer is x = 4.

A person invested $3,600 in an account growing at a rate allowing the money to
double every 7 years. How much money would be in the account after 17 years, to the
nearest dollar?

Answers

Answer:

$14400

Step-by-step explanation:

3600*2=7200 after the first 7 years

7200*2= 14400 after the next 7 years

17-14=3 years left after the first 14 years

The money in the account 17 years, to the nearest dollar is $20571.43.

Given that, a person invested $3,600 in an account growing at a rate allowing the money to double every 7 years.

What is the simple interest?

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Here, principal =$3600, money after 7 years= 2×3600 =$7200 and time period =7 years

2nd term:

Principal =$7200, money after 7 years = 2×7200=14,400

Thus, 17-14=3 years

Now, money for 3 years = 3/7 ×14,400

= $6171.43

So, money in the account after 17 years is

= 14400+6171.43

= $20571.43

Hence, the money in the account 17 years, to the nearest dollar is $20571.43.

(25 points!) Caleb bought a $795 necklace for his wife's birthday. If he bought it on credit with an interest rate of 16.25% how much total will he have paid after three years? ​

Answers

Answer:

The total amount that he would have paid after 3 years is $1183.

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

I represents interest paid on the amount owed.

P represents the principal or initial amount owed.

R represents interest rate

T represents the duration for which the amount was owed in years.

P = $795

R = 16.25

T = 3 years

I = (795 × 16.25 × 3) ÷ 100

I = $388

Total amount that he would have paid after 3 years is $795 + $388 = $1183

The total amount that he would have paid after three years would be $1183.

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

The given data as per the question

P = $795

R = 16.25

T = 3 years

Simple interest =  P × R × T

Substitute the values,

Simple interest = (795 × 16.25 / 100 × 3)

Simple interest = (795 × 0.1625 × 3)

Simple interest = $388

The total payback amount :  $795 + $388 = $1183

Therefore, the total amount that he would have paid after three years is $1183.

The pizza shop offers a 15 percent discount for veterans and senior citizens. If the price of a pizza is $12, how would you find the discounted price?

Answers

The discounted price of a pizza will be $1.8.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The pizza shop offers a 15 percent discount for veterans and senior citizens.

And, The price of a pizza = $12

Now,

Since, The price of a pizza = $12

And, The pizza shop offers a 15 percent discount for veterans and senior citizens.

Hence, The discounted price of pizza = 15% of $12

                                                          = 15 x 12 / 100

                                                          = $1.8
