A book publisher found that the cost to produce 1000 calculus textbooks is $25,600, while the cost to produce 2000 calculus textbooks is $50,300. Assume that the cost C(x)is a linear function of x, the Number of textbooks produced. What is the marginal cost of a calculus textbook?
A)$2.47
B)$0.02
C)$24,700.00
D)$24.70

The marginal cost is the change in cost divided by the change in quantity. Here, the change in cost is $50,300 - $25,600 = $24,700, and the change in quantity is 2000 - 1000 = 1000 textbooks. So, the marginal cost per textbook is $24,700 / 1000 = $24.70.
