a) Determine the variable cost per unit and the fixed cost using the high-low method.
b) What is the equation of the total mixed cost function?
c) Prepare the scatter diagram and insert the trendline or line of best-fit. Use a scale
of 2 cm to represent 1,000 units on the x-axis & 2 cm to represent $50,000 on the yaxis.
d) Using the line of best-fit, determine the company’s fixed cost per month and the
variable cost per unit. (Use 0 & 5,000 units.)
e) Which of the two methods appear more appropriate? Explain your answer.
