Answer:

$15

Step-by-step explanation:

The original price of the mirror is unknown, so let's call it x.

The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.

We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.

0.2x = 3

Divide both sides by 0.2.

x = 3/0.2

x = 15

The regular price is $15.

The regular price of a mirror with a 20% discount equivalent to $3 is $15

Percentage discount on price = 20%

The value of the discount = $3

Let the regular price of the mirror = r

The discount on the regular price can be expressed thus :

Percentage discount × regular price = discount value

20% × r = 3

0.2r = 3

Divide both sides by 0.2 to isolate r

0.2r / 0.2 = 3 / 0.2

r = $15

Hence, r = regular price of mirror = $15
