Your class hope 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. Write and inequality that describe the situation let's see represent the number of cancer food that must be collected by the end of the third week of your class to meet or surpass its goal. How many cans are needed to meet or surpass the goal?

1 answer

Let x be the number of cans of food that must be collected by the end of the third week.

The total number of cans collected after the first two weeks is 135 + 89 = 224 cans.

To meet or surpass the goal, the total number of cans collected by the end of the third week must be greater than or equal to 325 cans.

Therefore, the inequality that describes the situation is:
224 + x ≥ 325.

To find out how many cans are needed to meet or surpass the goal, we can solve for x by subtracting 224 from both sides of the inequality:

x ≥ 325 - 224,
x ≥ 101.

Therefore, at least 101 cans of food must be collected by the end of the third week in order to meet or surpass the goal.
