Question

1. a shop owner offered a 20% discount off the regular price of a mirror. the amount of the discount is $3. what is the regular price of the mirror? a. $15 b. $6 c. $9 d. $18

Explanation:

Step1: Define the discount relationship

Let the regular price be \( x \). A 20% discount means the discount amount is \( 0.20x \). We know the discount amount is $3. So we set up the equation \( 0.20x = 3 \).

Step2: Solve for x

To find \( x \), we divide both sides of the equation by 0.20: \( x=\frac{3}{0.20} \). Calculating this, \( \frac{3}{0.20}= 15 \).

Answer:

A. $15
