I need help on my homework
A company has found that the marginal cost
(in thousands of dollars) to produce x central
air conditioning units is C'(x)= 16x/2x^2+e
where x is the number of units produced.
(a) Find the cost function, given that the
company incurs a fixed cost of $15,000 even if
no units are built.
(b) The company will seek a new source of
investment income if the cost is more than
$22,000 to produce 5 units. Should they seek
this new source?
(a) What substitution should be used to
determine the cost function?
Use the quantity_
u=
as the substitution,
so that du=
dx
The cost function is C(x)=_
Therefore, the cost of producing 5 units is
so the company
source of investment income
seek a new
(Round to the nearest dollar as needed.)
