Amy bought a pair of running shoes she paid $66.09 during a 20% off sale, what is the regular price of the shoes?
Would I take 66.09 divide by 20%?

No. If you did this: 66.09/0.2 = 330.45.
Certainly the original price was not over $300.00
Please try again. 
would it be 79.30 66.09+20%

No. That isn't the answer, but at least it's close.
100%  20% = 80%
Let x = the original price.
0.8x = 66.09
x = 66.09/0.8
x = 
ok I get it the regular price is 82.61

Right.
