Question

Jackie and Marc went to dinner. The cost of their meal, not including tax and tip, was $45.00. Jackie had a coupon that reduced the cost of the meal to $36.00. What would the percent of tax be?

a. 10%
b. 15%
c. 20%
d. 25%

Answer 1

To determine the percent reduction from a coupon, subtract the discounted cost from the original cost to calculate the amount saved, then divide by the original cost and multiply by 100 to get the percentage. In this case, the percent of tax represented by the coupon is 20%.

Step-by-step explanation:

The student's question relates to calculating the percentage reduction applied to a meal's cost using a coupon. The original cost of the meal was $45.00, and after applying the coupon, the new cost became $36.00. To find the percent reduction, you subtract the discounted cost ($36.00) from the original cost ($45.00), which gives you the amount saved ($9.00). Then, you divide the amount saved by the original cost and multiply by 100 to get the percentage.

Here's the calculation:

Amount saved = Original cost - Discounted cost

Amount saved = $45.00 - $36.00

Amount saved = $9.00

Percent reduction = (Amount saved ÷ Original cost) × 100

Percent reduction = ($9.00 ÷ $45.00) × 100

Percent reduction = 0.20 × 100

Percent reduction = 20%

The percent of tax indicated by the coupon is 20%, which corresponds to option c.
