Which of the following individuals experiences the highest calorie cost?

A. Jordan, who weighs 145 pounds, and swims (0.058 cal/lb/min) for 35 minutes.
B. Trinity, who weighs 180 pounds, and walks on the treadmill (0.048 cal/lb/min) for 35 minutes.
C. Kacy, who weighs 120 pounds, and rides her bike (0.076 cal/lb/min) for 20 minutes.
D. Jaylen, who weighs 163 pounds, and plays soccer (0.097 cal/lb/min) for 25 minutes.
E. Luis, who weighs 185 pounds, and runs on the treadmill (0.094 cal/lb/min) for 25 minutes.

Luis experiences the highest calorie cost with a total of 434.5 calories burned from running on the treadmill for 25 minutes at a rate of 0.094 cal/lb/min given his weight of 185 pounds (Option E).

The student is asking which individual experiences the highest calorie cost. To find the answer, we calculate the total calories burned for each individual by multiplying their weight by the calorie cost per pound per minute and then by the duration of their activity in minutes.

Jordan: 145 lbs × 0.058 cal/lb/min × 35 min = 294.7 calories
Trinity: 180 lbs × 0.048 cal/lb/min × 35 min = 302.4 calories
Kacy: 120 lbs × 0.076 cal/lb/min × 20 min = 182.4 calories
Jaylen: 163 lbs × 0.097 cal/lb/min × 25 min = 395.075 calories
Luis: 185 lbs × 0.094 cal/lb/min × 25 min = 434.5 calories

Comparing these numbers, we conclude that Luis experiences the highest calorie cost from running on the treadmill.

Thus, the correct option is E.
