Question

The sale price is $46.75

Explanation:

Answer 2

20%

Explanation:

A pair of jeans cost $45 before the sale.

The sale is taking $9 off of the original price.

Then

$45 - 100%

$9 - x%

Write a proportion:

`(45)/(9)=(100)/(x)`

Cross multiply:

`45\cdot x=9\cdot 100\\ \\45x=900\\ \\x=(900)/(45)\\ \\x=20\%`
