I read that as
dC/dx = 16/(16x+3)^(1/3)
then C = (3/2)(16x + 3)^(2/3 + c
when x = 17, C=120
120 = (3/2)(275)^(2/3) + c
c = ....
Once you have c, you know C = ....
sub in x = 90
The marginal cost of a product is modeled by
dC/dx= 16/cube root 16x + 3
where x is the number of units. When x = 17, C = 120.
(a) Find the cost function. (Round your constant term to two decimal places.)
c=
(b) Find the cost of producing 90 units. (Round your answer to two decimal places.)
