A pair of sneakers are on sale for 20% off the original price. Tom purchased a pair of sneakers at this discounted price of $80. What is the original price of the sneakers?

write very professionally i need this for extra credit

Answers

The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100
well the answer to your question is 100!

This question is killing me plz help

Answers

Answer:

Males:

10.4% have green eyes.

33.3% have blue eyes.

56.3% have brown eyes.

Females:

7.5% have green eyes.

47.5% have blue eyes.

45% have brown eyes.

Explanation:

To find each percentage, we have to count up the amount of people for each gender.  When we have the males, we add them up and we get 48 males.  Now lets take green eyes and divide it by 48, since 5 ÷ 48 0.1041666666666667, we now multiply that number by 100 and we get 10.41666666666667.  Now round that number to the nearest ten and we get %10.4.  Now you know the formula, I hope you understand it. :)
