How would you solve the problem - A class wanted to collect 325 cans and on the first week they collected 135 cans, the second week they collected 89 more cans what will they need to collect on week three?

135 + 89 = ________

Subtract the sum from 325 to find how many cans to collect in week three.

To solve this problem, you need to find the amount of cans the class will need to collect on week three.

Step 1: Find the total number of cans collected after the first and second weeks.
- In the first week, the class collected 135 cans.
- In the second week, they collected an additional 89 cans.
- So, the total number of cans collected after the first and second weeks is 135 + 89 = 224 cans.

Step 2: Calculate the remaining number of cans needed to reach the goal of 325 cans.
- The class wanted to collect 325 cans.
- So, the remaining number of cans needed is 325 - 224 = 101 cans.

Therefore, the class will need to collect 101 cans on week three to reach their goal.
