Question

John has consumed 1,600 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 1,800 calories per day. How many calories does he have left to consume for the day? Is 1,000 a viable solution to this problem?

 A.No; 1,000 is more than the 400 he burned off at the gym.

 B.No; 1,000 will cause him to exceed 1,800.

 C.Yes; 1,000 is less than 1,600. 

D.Yes; 1,200 is less than 1,800.

Answer 1

If he consumed 1600 calories so far today and burned 400 at the gym, here is where he is at:

1600-400 = 1200 calories

If he wants to have a daily total of 1800, here is how many he has left:

1800-1200 = 600 calories left. So doesn't have 1,000 left, because:

B. No; 1,000 will cause him to exceed 1,800
