To produce a textbook, suppose the publisher spent $110,000 for typesetting and $7.50 per book for printing and binding. The total cost to produce and print n books can be written as C=110,000+7.5n a. Suppose the number of books printed in the first printing is 10,000. What is the total cost? The total cost is $. b. If the average cost is the total cost divided by the number of books printed, find the average cost of producing 10,000 textbooks. The average cost of producing 10,000 textbooks is $. c. Find the cost to produce one more textbook when you have already produced 10,000 textbooks. If you have already produced 10,000 textbooks, it'll cost you $ to produce one more.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
