What is the original price?

Answer 1

100-66= 34
Move decimal to left .34
Divide 108.80 by .34 = 320
So the original price is $320.

Answer 2

`\$320.29`

Explanation:

Determine the formula:

`x - (x * 0.66) = 108.90`

Solve for x to get the original price:

`x - (x * 0.66) = 108.90\\x - 0.66x = 108.90\\x(1-0.66) = 108.90\\x = (108.90)/(1-0.66)\\x = (108.90)/(0.34)\\x \approx 320.29`
