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 your goal.

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

A.
the sum of the all number of cans collected must be greater than or equal to 325:
135 + 89 + c >= 325
*note that >= is "greater than or equal to" symbol here. but the symbol must be really a greater than symbol with an underline.

B. we just solve for c.
224 + c >= 325
c >= 325 - 224
c >= 101

thus they need 101 cans to meet their goal.
