Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2
Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

c(x)=1000+ 90x- 0.2x^2

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = \frac{1000}{x} +90-0.2x

B) Marginal cost = dC/dx = 90-0.4x

When x=140 marginal cost = 90-0.4(140)\\=34

C) We calculate

c(140) = =1000+90(140)-0.2(140^2)\\\\=9680

c(141) = =1000+90(141)-0.2(141^2)\\\\\\=9713.80

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.
