某公司的短期总成本函数由等式TC=200+55q给出,式中,TC为总成本; q为总产出数量;两者均以千计。
(1)该公司的固定成本是多少?
(2)如果该公司生产了100000单位的产品,它的平均可变成本是多少?
(3)其所生产的单位产品的边际成本是多少?
(4)其平均固定成本是多少?
(5)假定该公司通过贷款扩大生产规模,其固定成本增加5000美元,但其可变成本降至每1000单位产品45000美元,利率i也进入成本函数。利率每上升1%,成本增加3000美元。写出新的成本函数。
The short - run cost function of a company is given by the equation TC = 200 +55q, where TC is the total cost and q is the total quaintly of output ,both measured in thousands.
a. What is the company' s fixed cost?
b. If the company produced 100000 units of goods, what is its average variable cost?
c. What would be its marginal cost of production?
d. What would be its average fixed cost?
e. Suppose the company borrow money and expands its factory. Its fixed cost rises by
$ 50000, but its variable cost falls to $ 45000 per 1000 units. The cost of interest (i) also enters into the equation. Each one-point increase in the interest rate raises costs by $ 3000. Write the new cost equation.
