Question

a pair of $120 shoes was discounted 20 percent. a customer had a coupon for an additional $5 off. what was the final price of the shoes?
○ $90
○ $91
○ $92
○ $96

Explanation:

Step1: Calculate 20% discount on $120

First, find 20% of $120. The formula for percentage is $ \text{Percentage of a number} = \frac{\text{Percentage}}{100} \times \text{Number} $. So, 20% of 120 is $ \frac{20}{100} \times 120 = 0.2 \times 120 = 24 $. Subtract this discount from the original price: $ 120 - 24 = 96 $.

Step2: Apply additional $5 off

Now, subtract the additional $5 coupon from the discounted price: $ 96 - 5 = 91 $.

Answer:

\$91 (corresponding to the option with \$91)
