Amy paid $63.75 for a pair of walking shoes during a 15%-off sale. What was the regular price? I am stuck on the same problem even after reading all the examples! I have a quiz due on Tuesday. I have tried dividing .85 into the sale price.

Do you want an explanation?

anonymous · Answer

x is the regular price
$63.75 is the regular price minus 15% of the regular price
x - (.15)x = 63.75
this can also be written as

(1 - .15)x = 63.75
I just factored out the x on the left side
(1 - .15) = .85 so
.85x = 63.75
x = 75
