Answer 1

Percent of decrease is `63%`

Explanation:

Original price is `$15` at `100%`

Sale price is `$5.50` at `x`

Then: `($15)/($5.50) = (100%)/x`

Cross multiply: `15x = 5.50*100%`

`x = (550%)/15 = 36.67%` Which is the sale price percent.

To find the percent of decrease we need to subtract the sale price percent from the original `100%`

`100% - 36.67.% = 63.3%` rounded off to `63%`
