# Cost The marginal cost of serving an additional typical client at a law firm can be modeled by d c d x = 675 + 0.5 x where x is the number of clients. Find the change in cost C (in dollars) when x increases from 50 to 51 clients.

To determine

To calculate: The change in cost when x increases from 50 to 51 clients, if the marginal cost is modeled by dCdx=675+0.5x.

Explanation

Given information:

The marginal cost is modeled by dCdx=675+0.5x where x is the number of clients.

Formula used:

Marginal analysis:

x1x2dRdxdx=R(x2)R(x1)

Calculation:

Consider the marginal cost dCdx=675+0.5x.

Use Marginal analysis where x2=51 and x1=50

5051(675+0
