A company is planning to manufacture snowboards. The fixed costs are $100 per day and total costs are $5700 per day at a daily output of 20 boards. C(x)=280x+100 B. The average cost per board for an output of x boards is given by C(x)=C(x)/x. Find the average cost function. 280x + 100 C(x)= X C. Sketch a graph of the average cost function, including any asymptotes, for 1x30. Choose the correct graph below. O A. OB. 500- 0+ 1 30 C. OD. y 500- 500- Q 500- Q 0+ 30 30 D. What does the average cost per board tend to as production increases? G 30 x
