amy paid 64.13 for a pair of running shoes during a 35% sale off. what was the regular price.

• math -

Let x = original price of the shoes.
Then the discount is 0.35x; therefore,
x - 0.35x = 65.13.
Solve for x.

i am stumped.

What's the problem? Can you solve the equation? If you can't, what don't you understand?

• math -

is it 64.48?

It can't be 64.48 because that's just a few cents more than the sale price.

I'll do it a little differently. Since it's 35% off, he's paying 65% of the original price.

0.65x = 64.13
0.65x/0.65 = 64.13/0.65
x = 98.66

Let's check that answer.

0.35 * 98.66 = 34.53

98.66 - 34.53 = 64.13

Yay! It's right! The original price was \$98.66.
