A company manufacturing snowboards has fixed costs of $200 per day and total costs of $3,800 per day at a daily output of 20 boards. A) Assuming that the total cost per day, C(x), is linearly related to the total output per day, x, write an equation for the cost function. = B) The average cost per board for an output of x boards is given by C(x) = average cost function. C) Sketch a graph of C(x), including any asymptotes, for 1 ≤ n ≤ 30. D) What does the average cost per board tend to as production increases? Find the
