Question

A team needs to save up at least $400 for new uniforms and currently has $210. They decide to hold a fundraiser where they can earn $7 in profits for each item sold. What inequality could be solved to determine the minimum number, n, of items to be sold?

Answer 1

they have 210 and they need at least 400. For every n they sell for 7 they will add to the existing 210. So the inequality will be\[210+7n \ge 400\]

Answer 2

That means that to the 210 they already have, they will add an unknown number of items they sell for $7 apiece. That amount needs to be at least $400.
