Solve the problem.The cost in producing a shipment of widgets that you supply to various regional businesses consists of a setup expense of $20 plus $0.24 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. How many widgets can you include in a shipment if you don't want to spend more than $104.00 making them?
A. C = 0.24x; 20 widgets can be
included in the shipment.
B. C = 20 + 0.24x; 20 widgets can be
included in the shipment.
C. C = 20 + 0.24x; 300 widgets can be
included in the shipment.
D. C = 20 + 0.24x; 350 widgets can be
included in the shipment.
