The woodworker sells rocking horses. His start-up costs, comprising tools, plans, and advertising, total $5500. Labor and materials for every horse cost $350.
(a) Compute woodworker's total cost, C, to make 1, 2, 5, 10, and 20 rocking horses. Graph C against n, number of rocking horses that he carves.
(b) Determine the formula for C in terms of n. What rate of change tells us about woodworker's expenses?
