# Checkpoint 8 Worked-out solution available at LarsonAppliedCalculus.comThe marginal cost of producing x units of a product is modeled by d C d x = 28 − 0.02 x . It costs $40 to produce one unit. Find the cost of producing 200 units. To determine To calculate: The cost of producing 200 units, when the marginal cost of producing x units is modeled as, dCdx=280.02x. If the cost to produce one unit is$40.

Explanation

Given Information:

The marginal cost of producing x units of a product is dCdx=280.02x. The cost of producing one unit is \$40.

Formula used:

The difference rule of integration [f(x)g(x)]dx=f(x)dxg(x)dx.

The simple power rule of integration, xndx=xn+1n+1+C.

Calculation:

Consider the marginal cost, dCdx=280.02x.

Integrate the provided rate of marginal cost.

(dCdx)dx=(280.02x)dx

Rewrite the above indefinite integral, use the difference integral rule, [f(x)g(x)]dx=f(x)dxg(x)dx.

(dCdx)dx=(280.02x)dx=28dx(0.02x)dx

Integrate the provided indefinite integral, use the simple power rule of integration xndx=xn+1n+1+C
