Question: Suppose that the total benefit and total cost from an activity are, respectively, given by the following equations: B(Q)=150+28Q-5Q² and C(Q)=100 + 8Q. (Note: MB(Q)=28-10Q and MC(Q)=8.)

a. Write out the equation for the net benefit

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?
