A competitive firm sells its output for $60 per unit. Assume that labor is the only input that varies for the firm. The marginal product of the 10th worker is 20 units of output per day; the marginal product of the 11th worker is 16 units of output per day. The firm pays its workers a wage of $150 per day. For the 11th worker, the value of the marginal product of labor is a. $960. b. $1,200. c. $2,400. d. $480.

David consumes two things: gasoline (q 1) and bread (q 2). david's utility function is u(q 1, q 2)equals70q 1 superscript 0.5 baseline q 2 superscript 0.5. let the price of gasoline be p 1, the price of bread be p 2, and income be y. derive david's demand curve for gasoline. david's demand for gasoline is q 1equals nothing.
