Question

A shop owner offered a 20% discount off the regular price of a mirror. The amount of the discount is $3.

Answer 1

The discounted price of the mirror is $2.4

Explanation:

To get the percent price of a number, remember that the percent is part of 100- in this case, part of one. So for a 20% discount, it would be the price times 0.2. When you do this, you get $2.4. Sorry if this explanation isn't too precise.
