Suppose a person is interested in starting up a small espresso stand and wants to estimate how much work it will take to make a profit. After doing a bit of research, she learns that it will cost about $340 a month for permits plus roughly $0.79 per cup for ingredients and employee salary. If the selling price averages $3.25 a cup, how many cups of coffee must our entrepreneur sell to break even? Solve this by graphing the cost function and revenue function on the same grid. Start from 0 and count by 25 on the horizontal axis and 50 on the vertical.
