Question

Your class hopes to collect at least 325 cans of food for the annual food drive. There were 135 cans donated the first week and 89 more the second week.

a. Write an inequality that describes this situation. Let c represent the number of cans of food that must be collected by the end of the third week for your class to meet or surpass its goal

b. How many cans are needed to meet or surpass the goal.

Answer 1

a. 325 ≤ 135 + 89 + c

b. c = 101

c is 101 because if 325 = 135 + 89, then we can just subtract those two from 325 (325 - 135 - 89), which gives a total of 101 more cans needed.

Hope this helped.
