9. A company’s marginal cost function is where x is the number of units. Find the total cost of producing units 144 to 625.
Anettt [7]

Answer:

total cost is $2444

Step-by-step explanation:

A company’s marginal cost function MC= \frac{94}{\sqrt{x} } is where x is the number of units

Marginal cost function is the derivative of cost function

to find the total cost of producing units , take integral of marginal cost function

\int\limits ^{625}_{144}{\frac{94}{\sqrt{x} } } \, dx

94(2\sqrt{x} ) with intervals 144 to 625

now plug in the values

94(2\sqrt{625})-94(2\sqrt{144})=2444

total cost is $2444
