A company is planning to manufacture snowboards. The fixed costs are $400 per day and total costs are $5400 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. C(x) = 300 + 240x

An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.

bThe average rate of change of the linear function f(x)=3x+5 between any two points is ________.
