You pay 15 dollars for something that was 25% off. What was the original price of the hat before the discount?

20

Step-by-step explanation:

So we first subtract 25% from 100% so we can see what percent 15 is:

100 - 25 = 75 so 15 is 75% of ___:

This gives us a standard percentage problem, so:

75% = 0.75

we can rewrite the equation as a one-step equation:

15 = 0.75a

Dividing both sides by 0.75 and swapping sides gives

a = 15 ÷ 0.75 = 20

So the original price of the hat was $20

OR

because 25% is 1/4, and 75% is 3/4 and 15 is therefore 3/4:

15 ÷ 3 = 5

5 x 4 = 20

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
