A 25-year old woman burns 250 − 70 t cal/hr while walking on her treadmill. Her caloric intake from drinking Gatorade is 145 t calories during the t th hour. What is her net decrease in calories after walking for 2 hours?

The net caloric decrease in women after 2 hours of exercise is 215 calories.

Explanation:

Given that a woman burns 250 - 70 calories per hour walking on her treadmill, and her caloric intake is 145 calories when drinking Gatorade, to determine her net caloric decrease after two hours of exercise, the following calculation should be performed:

((250 - 70) x 2) - 145 = X

(180 x 2) - 145 = X

360 - 145 = X

215 = X

Thus, the net caloric decrease in women after 2 hours of exercise is 215 calories.
