1. Original price-- $80
Percent of discount—20%
Sale price-- ???

Convert 20% to a decimal by dividing by 100, = 0.20 Multiply that by $80
80 x 0.20 = $16 discount.
80 - 16 = $64 sale price

Or you can say after you take 20% away, you have 80% left. Multiply $80 x 0.80 = $64

2.Original price-- $82
Percent of discount-- ???
Sale price-- $65.60

Full price x percent left after discount = sale price
82x = 65.60 divide both sides by 82
x = 0.8
Multiply that times 100 to get the percentage,
x = 80%

3. Original price-- ???
Percent of discount—5%
Sale price-- $57

5% off leaves us 95% to pay = 0.95
0.95x = 57
x = $60

4.A store pays $85 for a game system. They mark it up 125%. If 6% sales tax is applied on top of the new price, what is the final price of the aquarium?
85 x 1.25 = 106.25
106.25 x 0.06 = 6.375 added
106.25 + 6.375 = 112.625 = $112.63

5. Your friend used a $20 coupon to purchase a pair of sneakers that were advertised at $139.99. You buy the same shoes, but you use a 20% off coupon. Who paid a cheaper price?

Remember that 20% off = paying 80%

139.99 - 20 = $119.99
139.99 x 0.8 = $111.99

You pay a cheaper price

6. A store buys an item for $10. To earn a profit of $25, what percent does the store need to markup the item?

$10 cost + $25 profit = $35 new price
So we need percent difference between 10 and 35

10x = 35
x = 3.5, multiply by 100 to get the percentage = 350%

7.You and 2 friends go out to dinner. The food bill comes to $35.20, and you are charged an additional 6% sales tax. You then want to leave an 18% tip just on the price of the food. If you split the final amount evenly, how much should each person pay?

Well, we can ignore the tax part and look at the price of the food + price of the food x 18%
35.20 x 1.18 = 41.536
41.54 divided by 3 people = $13.85 per person

8.You start the baseball season with 10 strikeouts. By the end of the season, you only have 4 strikeouts. What is the percent of change of the number of strikeouts? (don’t forget increase or decrease!)

10x = 4
x = 0.4 = 40% decrease.

Someone help me on this please Every fossil tells a story. A paleontologist is a scientist who studies fossils to learn what life was like on planet Earth long ago. Fossilized footprints help us understand an animals anatomy, size, weight and even behavior. We can see if it traveled in groups or tended to live alone. Fossilized teeth can give us hints about an animals diet. We can even learn about the landscape where a plant or animal lived. If there are fish fossils in what is now a desert, we might hypothesize that the landscape was once a body of water. Learning more about those fish fossilslike their age and what kind of water they lived inwill help us learn even more.Paleontologist are most like detectives who use fossils asA. clues.B. theories.C. suspects.D. witnesses. In late 2020, the Nicklaus Corporation was formed. The corporate charter authorizes the issuance of 6,000,000 shares of common stock carrying a $1 par value, and 2,000,000 shares of $5 par value, noncumulative, nonparticipating preferred stock. On January 2, 2021, 4,000,000 shares of the common stock are issued in exchange for cash at an average price of $10 per share. Also on January 2, all 2,000,000 shares of preferred stock are issued at $20 per share.Required:1. Prepare journal entries to record these transactions.2. Prepare the shareholders' equity section of the Nicklaus balance sheet as of March 31, 2021.

Since the new par value is one-half the amount of the old, this represents a 2-for-1 stock split. That is, the shareholders will receive two shares of the $0.50 par stock in exchange for each share of the $1 par stock they own. The $1 par stock will be collected and destroyed by the issuing corporation.On November 1, 2021, the Nicklaus Corporation declares a $0.18 per share cash dividend on common stock and a $0.35 per share cash dividend on preferred stock.

Monarch butterfly larvae feed on Asciepias sp. but are not harmed by the cardenolides. Instead these molecules accumulate in the tissues of the caterpillar and are present in the tissues of the adult butterfly. Because of these toxins in their tissues, Monarch butterflies are unpalatable to insectivorous birds. Another species of butterfly, the Viceroy, looks very similar to the Monarch in its bright coloration and distinctive patterning but was thought to lack a toxin. Because Monarch butterflies are toxic it was long thought that the similar appearance of nontoxic Viceroy butterflies was an example of: The class decides to make chocolate chip cookies for Mr. Burns first day of school in September.
