a. Net benefits are N(Q) = 20 + 24Q – 4Q2.
b6 b6 b6 b6 b6 b6 b6 b6 b6
b. Net benefits when Q = 1 are N(1) = 20 + 24 –
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6
4 = 40 and when Q = 5 they are N(5) = 20 + 24(5) – 4(5)2 = 40.

c. Marginal net benefits are MNB(Q) = 24 – 8Q. b6 b6 b6 b6 b6 b6 b6 b6
d. Marginal net benefits when Q 1 are MNB(1) = 24 – 8(1) = 16 and when 5Q

b6 b6 b6 b6 b6 b6 b6 b6
e. Setting MNB(Q) = 24 – b6 b6 b6 b6

a. Total benefit when Q = 2 is B(2) = 20(2) –

b. Marginal benefit when Q = 2 is MB(2) = 20 – b6 b6 b6 b6 b6 b6 b6 b6 b6 b6
4(2) = 12. When Q = 10, it is MB(10) = 20 – 4(10) = -20.
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6
c. The level of Q that maximizes total benefits satisfies MB(Q) = 20 – 4Q = 0, so Q
