Question

I have two questions. I am trying to use the formulas our teacher used but I am still confused. I will discuss it with him tonight but I just wanted to get a different perspective.

#1
Amy paid $102 for a pair New Balance 1122 running shoes during a 15%-off sale. What was the regular price?

#2
The perimeter of the state of Wyoming is 1280 mi. The width is 90 mi less than the length. Find the width and the length.

Thanks.

errrgg..i meant i figured out #2 i need help with #1.

My formula is as instructed.

B=a/p (Base=amount/percent)

My answer is:

B=102.00/0.15

B=6.80

so the regular prices is 102.00+6.80=108.80

Is that correcT?

Thanks. I was translating the problem incorrectly. I got the right answer using the formula

A=P*B

A=15*102

A=15.30

15.30 + 102.00 = 117.30

Thanks.
