Mr. Herman's class is selling candy for school fundraiser. The class has a goal for raising $500 by selling c boxes of candy. For every box they sell, they make $2.75.

The goal is to raise $500.

For selling c boxes, they make $2.75,

Total made = $ 2.75c

For them to be able to make the $500,

2.75c ≥ 500

c ≥ 500 / 2.75

c ≥ 181.82

For them to reach and exceed their target, the number of boxes should be greater than 181.82

So c should be like 182, 183, 184, and above

Hope this clarifies it.

They need to sell 182 boxes because 181 boxes won't be enough to reach the goal.
