Solve the problem.The cost of manufacturing a molded part is related to the quantity produced during a production run. When 100 parts are produced, the cost is $300. When 600 parts are produced, the cost is $4800. Write a linear equation in point-slope form that gives the relationship between the number of parts produced and the cost of manufacturing.
A. y - 300 = 0.11(x - 100) or y - 4800 = 0.11(x - 600) B. y - 300 = 10.00(x - 100) or y - 4800 = 10.00(x - 600) C. y - 300 = 9.00(x - 100) or y - 4800 = 9.00(x - 600) D. y - 300 = 7.50(x - 100) or y - 4800 = 7.50(x - 600)
