Question

Joe is eating M&Ms. He eats 3 at a time, since he's very organized, and eats them at the beginning of every minute. If his bag of M&Ms originally had 100 candies, then which expression shows how many candies he has left, after T minutes?
A. M = 100+3t

B. M = 3+100t

C. M = 100 - 3t

D. M = 100 - t

Answer 1

Your answer would be C. M = 100 - 3t

Answer 2

C 

M=100-3t 

he eats 3 candies per minuter so if they were to give you the amount of minutes you would just have to subtract it from 100 to get the amount of candies he has left
