A school is having a canned food drive. Each class is challenged to collect 200 cans. If there are c classes in the school, which equation could be used to find the total number of cans, T, the school will collect if each class meets the challenge? A. T= c/200 B. T=200/c

C. 200c

D. 200+c

Answers

The answer would be C. 200c. This is because in order to find the answer you multiply the number of cans (200) by the number of classes (c) to get the total (t) for the school. Therefore, your equation would be: T= 200c
