Answer 2

$82.50

Explanation:

Francis heard that a car stereo system was on sale for 30% off.

The sale price was $57.75.

Let the original price of the car stereo system be 'x'

sale price = x - (30% of x) = 57.75

x - 0.3x = 57.75

0.7x = 57.75

x =
`(57.75)/(0.7)`

x = 82.5

The original price of the stereo system was $82.50.
