He believes that he needs to better understand the cost of the frames for pricing purposes. You have collected the following data concern- ing actual production over the past year: Month January February March April May June July August September October November December Number of Frames Produced 1,600 7,200 3,920 1,200 3,200 2,600 2,200 3,600 4,560 5,880 6,560 800 Total Cost $42,000. 65,000 59,000 37,200 58,000 54,000 51,200 62,000 64,000 63,000 64,000 33,000 b. Using the high-low method, compute the total cost equation for the preceding data. (1) Compute the variable cost per unit. (2) Compute total fixed costs. (3) Sketch a line between the high and low points on your graph. (4) Using the high-low method, estimate the total cost to produce 4,000 units.
