Solve the problem.The cost of producing a shipment of widgets that you supply to various regional businesses consists of a setup expense of $20 plus $0.20 per widget. Let C be the total cost of producing a shipment, and let x represent the number of widgets in a shipment. Write in symbolic form an equation that will relate C and x. Generate five data points from this equation using equally incremented x values ranging from 100 to 500, and use this data to plot a graph. What is the cost of producing a shipment of 350 widgets?
A. C = 20 + 0.20x; The cost of producing a
shipment of 350 widgets is $100.00.
B. C = 0.20x; The cost of producing a
shipment of 350 widgets is $70.00.
C. C = 20 + 0.20x; The cost of producing a
shipment of 350 widgets is $90.00.
D. C = 20 + 0.20x; The cost of producing a
shipment of 350 widgets is $70.00.
