Answer 1

$82.5

Explanation:

$82.5

Step-by-step explanation:

We can calculate it with a direct rule of 3. As it has a 30% off, the remaining price is the 70% and we want to know how much is the 100%

We use the formula of the direct rule of 3

x = 82.5

The original price of the stereo was $82.5
