Suppose that the total benefit and total cost from an activity are, respectively, given by the following equations: B(Q) = 150 + 28Q - 5 Q₂ and C(Q) = 100 + 8Q. (Note: MB(Q) = 28 - 10 Q and MC(Q) = 8.)
a. Write out the equation for the net benefits.
b. What are the net benefits when Q = 1 Q = 5
c. Write out the equation for the marginal net benefits.
d. What are the marginal net benefits when Q = 1 Q = 5
e. What level of Q maximizes net benefits
f. At the value of Q that maximizes net benefits, what is the value of marginal net benefits
