Chapter 10, Problem 10.29E

Linear cost approximation. Dr. Young, of Young and Associates, LLP, is examining how overhead costs behave as a function of monthly physician contact hours billed to patients. The historical data are as follows:

Total Overhead Costs Physician Contact Hours Billed to Patients
$ 90,000 150
105,000 200
111,000 250
125,000 300
137,000 350
150,000 400
  1. 1. Compute the linear cost function, relating total overhead costs to physician contact hours, using the representative observations of 200 and 300 hours. Plot the linear cost function. Does the constant component of the cost function represent the fixed overhead costs of Young and Associates? Why?

    Required

  1. 2. What would be the predicted total overhead costs for (a) 150 hours and (b) 400 hours using the cost function estimated in requirement 1? Plot the predicted costs and actual costs for 150 and 400 hours.
  2. 3. Dr. Young had a chance to do some school physicals that would have boosted physician contact hours billed to patients from 200 to 250 hours. Suppose Dr. Young, guided by the linear cost function, rejected this job because it would have brought a total increase in contribution margin of $9,000, before deducting the predicted increase in total overhead cost, $10,000. What is the total contribution margin actually forgone?

The administrator of Azalea Hills Hospital would like a cost formula linking the administrative costsinvolved in admitting patients to the number of patients admitted during a month. The Admitting Department’s costs and the number of patients admitted during the immediately preceding eight months are givenin the following table:Number of AdmittingMonth Patients Admitted Department CostsMay ........................... 1,800 $14,700June .......................... 1,900 $15,200July ........................... 1,700 $13,700August ....................... 1,600 $14,000September ................ 1,500 $14,300October ..................... 1,300 $13,100November ................ 1,100 $12,800December ................. 1,500 $14,600Required:1. Use the high-low method to estimate the fixed and variable components of admitting costs.2. Express the fixed and variable components of admitting costs as a cost formula in the formY a bX .
Show a detailed, step by step process for the following question below:   “Apollo is a local hospital that offers two types of procedures. Currently, Apollo uses a simple system to calculate the overhead cost per treatment. This is done by taking the total overhead cost and dividing it by the number of treatments. Using this method, the full cost for each procedure is shown below:   Procedure X Y Direct costs per procedure £2,610 £1,560 Full cost per procedure £2,831 £1,781   Recently, another competitor has implemented activity based costing (ABC). This has led the finance director to consider whether this alternative costing technique would bring any benefits. She has obtained an analysis of Apollo’s total overheads for the last year and some additional data, all of which is shown below:”   Cost Cost driver    Administrative costs Administrative time per procedure £935,080 Nursing costs Length of patient stay £3,127,808 Catering…
