Final answer:
Based on the equation T = 2000 + 500h, if you spend 3 hours exercising, you should consume 3500 calories.
Step-by-step explanation:
To determine the number of calories you should consume based on the equation T = 2000 + 500h, you need to substitute the value of h with the number of hours you spend exercising. In this case, h is 3 hours. So, you have T = 2000 + 500(3) which simplifies to T = 2000 + 1500. Adding these two values, you get T = 3500 calories. Therefore, based on the given equation, you should consume 3500 calories.
