Question

Your friend buys a skateboard that is on sale for one third off the original price. Your friend spent $36 than the original price. What was the original price of the skateboard?

Answer 1

original price of skateboard = $54

Explanation:

Let the original price of the skateboard be x

selling price = one third off the original price = $36

x - (1/3x) = 36

`(x)/(1) - (x)/(3) = (3x-x)/(3) = (2x)/(3)`

`(2x)/(3) = 36\\2x = 108\\x = (108)/(2) = 54`

∴ x = 54
