The tennis team is selling key chains as a fundraiser. if its goal is to raise at least $180, how many key chains must sell at $2.25 each to meet that goal? write and solve the inequality.

A. The answer is our unit prices when our profit is 0

Step-by-step explanation:

The zeros are the x-intercepts, when the curve passes through the x-axis.

I'm going to call our function P

P(x)=-0.5x^2+221x-224 is equal to 0 (our profit is equal to 0) when x (the unit price is such and such)

The answer is our unit prices when our profit is 0
