Question

Quizplus · Accepted Answer

To find the average number of Calories Matthew consumed in excess of his body's needs per day, we need to determine the total number of Calories he consumed above his body's needs and divide by the number of days in the 21-day period. One pound of body weight represents approximately 3,500 Calories, so 5 lb represents 5 × 3,500 = 17,500 Calories. Dividing by 21 yields 834 Calories per day. The closest choice to this answer is C, 833.
