Case 5A-11 Mixed Cost Analysis and the Relevant Range LO5

The Ramon Company is a manufacturer that is interested in developing a cost formula to estimate the variable and fixed components of its monthly manufacturing overhead costs. The company wishes to use machine-hours as its measure of activity and has gathered the data below for this year and last year:

    Last Year This Year
    Machine Overhead Machine Overhead
    Month Hours Hours Hours Costs
    January 21,000 $84,000 21,000 $86,000
    February 25,000 $99,000 24,000 $93,000
    March 22,000 $89,500 23,000 $93,000
    April 23,000 $90,000 22,000 $87,000
    May 20,000 $81,000 20,000 $80,000
    June 19,000 $75,000 18,000 $76,000
    July 14,000 $70,000 12,000 $67,000
    August 10,000 $64,000 13,000 $71,000
    September 12,000 $69,000 73,000 $73,500
    October 17,000 $75,000 17,000 $72,500
    November 16,000 $71,500 15,000 $71,000
    December 19,000 $78,000 18,000 $75,000

The company leases all of its manufacturing equipment. The lease arrangement calls for a flat monthly fee up to 19,500 machine-hours. If the machine-hours used exceed 19,500, then the fee becomes strictly variable with respect to the total number of machine-hours consumed during the month. Lease expense is a major element of overhead cost.<

Required:

Using the high-low method, estimate a manufacturing overhead cost formula in the form Y= a + bX.

Prepare a scatter graph using all of the data for the two-year period. Fit a straight line or lines to the plotted points using a ruler. Describe the cost behavior pattern revealed by your scatter graph plot.
Assume a least-squares regression analysis using all of die given data points estimated the total fixed cost to be $40,102 and the variable cost to be $2.13 per machine-hour. Do you have any concerns about the accuracy of the high-low estimates that you have computed or the least-squares regression estimates that have been provided?
Assume that the company consumes 22,500 machine-hours during a month. Using the high-low method, estimate the total overhead cost that would be incurred at this level of activity. Be sure to consider only the data points contained in the relevant range of activity when performing your computations.
Comment on the accuracy of your high-low estimates assuming a least-squares regression analysis using only the data points in the relevant range of activity estimated the total fixed cost to be $10,090 and the variable cost to be $3.53 per machine-hour.

Question 6 Amundsen Company makes 60,000 units per year of a part it uses in the products it manufactures. The unit product cost of this part is computed as follows: Direct Materials Direct Labor Variable Manufacturing Overhead Fixed Manufacturing Overhead Variable Selling Fixed Selling Total $ 10.10 $17.40 $ 2.70 $15.00 $ 2.75 $ 3.25 $51.20 An outside supplier has offered to sell the company all of these parts it needs. If the company accepts this offer, the facilities now being used to make the part would be idle and fixed manufacturing overhead would be reduced by 80% of current cost. The variable selling costs would be reduced to 40% of current cost. Required: What is the maximum amount the company should be willing to pay an outside supplier per unit for the part?
