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 equality that describes the 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?
89 + 135 + c = 325
Calculate for c.

a. To write an equality that describes the situation, let's break down the information given.
- The class hopes to collect at least 325 cans of food.
- 135 cans were donated in the first week.
- 89 more cans were donated in the second week.
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.
To calculate the total number of cans collected, we need to add up the cans from each week and compare it to the goal:
Total number of cans collected = Cans donated in the first week + Cans donated in the second week + Cans donated in the third week
Therefore, the equality that describes the situation is:
c cans = 135 cans + 89 cans + Cans donated in the third week
b. To find out how many cans are needed to meet or surpass the goal, we subtract the total cans collected from the goal:
Goal - Total number of cans collected = Cans needed to meet or surpass the goal
Therefore, to find out how many cans are needed, we would subtract the total number of cans collected from the goal of 325 cans.
