  1. Suppose the total benefit derived from a given decision, QQQ, is B(Q)=25Q−Q2B(Q) = 25Q - Q^2B(Q)=25Q−Q2 and the corresponding total cost is C(Q)=5+Q2,C(Q) = 5 + Q^2,C(Q)=5+Q2, so that MB(Q)=25−2Q and MC(Q)=2Q.MB(Q) = 25 - 2Q \text{ and } MC(Q) = 2Q.MB(Q)=25−2Q and MC(Q)=2Q.

a. What is total benefit when Q=2Q = 2Q=2? Q=10Q = 10Q=10?
