Continuing the previous problem, use Goal Seek for each value of number mailed $($once for $80,000,$ once for $90,000,$ and so on$).$ For each, find the response rate that allows the company to break even. You may chart these values, where the number mailed is on the horizontal axis, and the breakeven response rate is on the vertical axis. Explain the behavior in this chart in a brief memo to management.
