A firm can use 180 workers and 45 machines, 150 workers and 60 machines, or 210 workers and 27 machines to produce 150 desks. If each worker costs $90 and each machine is rented for $1,800, the economically efficient input combination is: a) 210 workers and 27 machines
b) none of the available answers is correct
c) 150 workers and 60 machines
d) 180 workers and 45 machines

Which of the statements best describes why the aggregate demand curve is downward sloping? an increase in the aggregate price level causes consumer and investment spending to fall, because consumer purchasing power decreases and money demand increases. as the aggregate price level increases, consumer expectations about the future change. as the aggregate price level decreases, the stock of existing physical capital increases. as a good's price increases, holding all else constant, the good's quantity demanded decreases.

Describe what fixed costs and marginal costs mean to a company.

Amonopolist’s inverse demand function is p = 150 – 3q. the company produces output at two facilities; the marginal cost of producing at facility 1 is mc1(q1) = 6q1, and the marginal cost of producing at facility 2 is mc2(q2) = 2q2.a. provide the equation for the monopolist’s marginal revenue function. (hint: recall that q1 + q2 = q.)mr(q) = 150 - 6 q1 - 3 q2b. determine the profit-maximizing level of output for each facility.output for facility 1: output for facility 2: c. determine the profit-maximizing price.$
