Answer: $15
Step-by-step explanation:
The normal price of the mirror is unknown we do not know that yet. So, let y represent the unknown number. The discount is 20 percent, we turn 20 into a decimal which would be 0.2. The amount of discount is $3. So, 0.2y equals to $3.
Then we divided.
y = 3 ÷ 0.2
And when you divide that is would be 15.
So, the regular price of the mirror is $15.
The easiest way I know is to multiply the divisor by different numbers to see how many times it will go into the dividend. multiplying 486 by 2 or three and seeing which one gets closest.
