ACT 5060 homework 2 Problems 2015

1. Computing Average Unit Costs
The total monthly operating costs of Chili To Go are:

$8,000+ $0.30X

where

X = servings of chili

Round answers to one decimal place.

Volume	Average Unit Cost
100	$Answer
1,000	$Answer
5,000	$Answer
10,000	$Answer

(b) Determine the monthly volume at which the average cost per serving is $0.70.
Answer servings of chili

2. Automatic versus Manual Processing
Photo Station Company operates a printing service for customers with digital cameras. The current service, which requires employees to download photos from customer cameras, has monthly operating costs of $6,000 plus $0.20 per photo printed. Management is evaluating the desirability of acquiring a machine that will allow customers to download and make prints without employee assistance. If the machine is acquired, the monthly fixed costs will increase to $10,000 and the variable costs of printing a photo will decline to $0.04 per photo.

(a) Determine the total costs of printing 20,000 and 50,000 photos per month.

Units	Current Process	Proposed Process
20,000	$Answer	$Answer
50,000	$Answer	$Answer

(b) Determine the monthly volume at which the proposed process becomes preferable to the current process.
Answer units

3. High-Low Cost Estimation
Assume the local DHL delivery service hub has the following information available about fleet miles and operating costs:

Year	Miles	Operating Costs
2012	556,000	$182,000
2013	684,000	214,000

Use the high-low method to develop a cost-estimating equation for total annual operating costs. (Let X = annual fleet miles.)

Total annual costs = Answer + Answer * X

4. Cost Behavior Analysis in a Restaurant: High-Low Cost Estimation
Assume a Papa John's restaurant has the following information available regarding costs at representative levels of monthly sales:

	Monthly sales in units
	5,000	8,000	10,000
Cost of food sold	$10,000	$16,000	$20,000
Wages and fringe benefits	5,150	5,240	5,300
Fees paid delivery help	1,150	1,840	2,300
Rent on building	1,400	1,400	1,400
Depreciation on equipment	800	800	800
Utilities	700	760	800
Supplies (soap, floor wax, etc.)	250	340	400
Administrative costs	1,200	1,200	1,200
Total	$20,650	$27,580	$32,200

(a) Identify each cost as being variable, fixed, or mixed.

5. Developing an Equation from Average Costs
The America Dog and Cat Hotel is a pet hotel located in Las Vegas. Assume that in March, when dog-days (occupancy) were at an annual low of 400, the average cost per dog-day was $18. In July, when dog-days were at a capacity level of 4,000, the average cost per dog-day was $9.

(a) Develop an equation for monthly operating costs. (Let X = dog-days per month)
Total cost = Answer + Answer * X

(b) Determine the average cost per dog-day at an annual volume of 24,000 dog-days.
$Answer

6. Multiple Cost Drivers
Scottsdale Ltd. manufactures a variety of high-volume and low-volume products to customer demand. Presented is information on 2013 manufacturing overhead and activity cost drivers.

Level	Total Cost		Units of Cost Driver
Unit	$ 500,000		10,000 machine hours
Batch	100,000		500 customer orders
Product	200,000		25 products

Product X1 required 2,000 machine hours to fill 10 customer orders for a total of 8,000 units.

(a) Assuming all manufacturing overhead is estimated and predicted on the basis of machine hours, determine the predicted total overhead costs to produce the 8,000 units of product X1.
$Answer

(b) Assuming manufacturing overhead is estimated and predicted using separate rates for machine hours, customer orders, and products (a multiple-level cost hierarchy), determine the predicted total overhead costs to produce the 8,000 units of product X1.
$Answer

(c) Calculate the error in predicting manufacturing overhead using machine hours versus using multiple cost drivers. Indicate whether the use of only machine hours results in overpredicting or underpredicting the costs to produce 8,000 units of product X1.
$Answer Answer

(d) Determine the error in the prediction of X1 batch-level costs resulting from the use of only machine hours. Indicate whether the use of only machine hours results in overpredicting or underpredicting the batch-level costs of product X1.
$Answer Answer

(e) Determine the error in the prediction of X1 product-level costs resulting from the use of only machine hours. Indicate whether the use of only machine hours results in overpredicting or underpredicting the product-level costs of product X1.
