Academy Products manufactures a variety of custom components for use in aircraft navigation and communications systems. The controller has asked for your help in estimating fixed and variable overhead costs for Academys Rio Puerco plant. The controller tells you that the best cost driver for estimating overhead is machine-hours. Monthly data on machine-hours and overhead costs for the last year have been collected and are shown below: Month Machine-Hours Overhead Costs 1 630,000 $ 660,000 2 900,000 2,170,000 3 765,000 1,220,000 4 665,000 780,000 5 1,035,000 3,700,000 6 800,000 1,400,000 7 750,000 1,100,000 8 815,000 1,500,000 9 935,000 2,500,000 10 680,000 840,000 11 715,000 980,000 12 700,000 910,000 Required: a. Estimate the monthly fixed costs and the unit variable cost per machine-hour using the high-low estimation method. (Round variable cost per unit to 4 decimal places.) b. Draw a scattergraph relating overhead costs to the number of machine-hours. Instructions: 1. On the graph below, use the point tool to plot the point corresponding to the machine-hours and relating overhead costs (Month 1). 2. Repeat the process for the remainder of the sample (Month 2, Month 3, ). 3. To enter exact coordinates, double click on the point and enter the exact co-ordinates of x and y.
