Are you in calculus?

No, I'm in algebra 2

radar · Answer

If you are, then differentiate the function set the derivative to equal zero and do the minimum test.

radar · Answer

So algebra II huh.  Then I guess you would need a graphing calculator and graph and see

radar · Answer

The derivative methos says 60 bats required to minimize cost. Using that number the cost appears to be $174. Or 174 units of currency.
