Sure! Let's break down the solution step-by-step:
1. Identify the original cost and the discount rate:
- Mr. Dupree bought [tex]$14 worth of food.
- He used a coupon for a 15% discount.
2. Calculate the discount amount:
- The discount amount can be found by multiplying the original cost by the discount rate.
- Discount amount = $[/tex]14 * 0.15 = [tex]$2.10
3. Subtract the discount amount from the original cost:
- Final cost = Original cost - Discount amount
- Final cost = $[/tex]14 - [tex]$2.10 = $[/tex]11.90
So, Mr. Dupree ended up paying [tex]$11.90 for the food after applying the 15% discount.
Thus, the correct answer is:
(b) $[/tex]11.90
