Answer 1

This question in short is asking how many calories are burned after playing playing basketball for 30 minutes. At a rate of 15 calories per minute for 30 minutes, Carla will have burned 450 calories. Burning calories by exercising uses energy, so the change in the calories will be negative. If Carla were eating food then the number would be positive because they would be gaining calories.
