10K L%. 1). Consider the production function Q = (a) What is the output when K = 100000 and L = 243? (b) Use the marginal analysis to estimate Q(99995, 243) and Q(100000, 245). (c) Use a calculator to compute these two values of Q to three decimal places and compare these values with your estimates in (b). (d) How big must AL be in order for the difference between Q(100000, 243+AL) and its linear approximation Q(100000, 245) + -DAL, to differ by more than two units?
You are given the following cost functions: TC=100+60Q−3Q2+0.1Q3TC=100+60Q−3Q2+0.1Q3 TC=100+60Q+3Q2TC=100+60Q+3Q2 TC=100+60QTC=100+60Q b). In each case, indicate the point at which diminishing returns occur. also indicate the point of maximum cost efficiency (i.e., the point of minimum average cost). c). For each function, discuss the relationship between marginal cost and average variable cost and between marginal cost and average. Discuss the relationship between average variable cost and average cost.

A company has established that the relationship between the sales price for one of its products and the quantity sold per month is approximately p = 77 – 0.12D units. The fixed cost is $800 per month and the variable cost $25 per unit produced. What number of units, D*,should be produced per month and sold to maximize the profit per month related to the product? Round your answer to 2 decimal places.
