Explanation:

1.

Step1: Find amount of discount

Discount amount = Original price - Sale price. So, $40 - 24=16$.

Step2: Calculate percent - discount

Percent - discount = $\frac{\text{Discount amount}}{\text{Original price}}\times100\%$. Substitute values: $\frac{16}{40}\times100\% = 40\%$.

Step1: Find 5% of 13 ounces

$5\%$ of 13 ounces is $0.05\times13 = 0.65$ ounces.

Step2: Calculate weight of large bag

Weight of large bag = Weight of small bag+5% of weight of small bag. So, $13 + 0.65=13.65$ ounces.

Step1: Determine number of drivers

Ethan and four friends means $1 + 4=5$ drivers.

Step2: Calculate total time

If one driver drives for 32.5 minutes, then total time = Number of drivers×Time per driver. So, $5\times32.5 = 162.5$ minutes.

Answer:

a. 40%
