Suppose that the monthly​ cost, in​ dollars, of producing x chairs is ​C(x)=0.001x^3+0.07x^2+16x+600, and currently 90 chairs are produced monthly.

​a)
What is the current monthly​ cost?
​b)
What is the marginal cost when x= 90​?
​c)
Use the result from part​ (b) to estimate the monthly cost of increasing production to 92 chairs per month.
​d)
What would be the actual additional monthly cost of increasing production to 92 chairs​ monthly?

Consider a firm that is currently producing 600 sofas a month. The monthly fixed cost is $1,920, while the average total cost is $72 (the average total cost curve has the usual shape). Producing the 600th sofa increased the firm’s total costs by $70. At Q = 600, is the firm’s average variable cost curve upward sloping, horizontal, downward sloping, or vertical? Why? Explain clearly your reasoning in words.
