A companys marginal cost function is 20Squareroot x where x

A company\'s marginal cost function is 20/Squareroot x where x is the number of units. Find the total cost of the first 25 units (from x = 0 to x = 25) Total cost: $ Preview

Solution

Company’s marginal cost function = f(x) = 20/x

Then total cost of first 25 units = (20/x)*dx          [0 to 25]

                                               = 40*x                   [0 to 25]

                                                = 40*[5 - 0] = $200
