The controller for Dohini Manufacturing Company felt that the number of purchase orders alone did not explain the monthly purchasing cost. He knew that nonstandard orders (for example, one requiring an overseas supplier) took more time and effort. He collected data on the number of nonstandard orders for the past 12 months and added that information to the data on purchasing cost and total number of purchase orders.

Using Multiple Regression Results to Construct and Apply a Cost Formula

The controller for Dohini Manufacturing Company felt that the number of purchase orders alone did not explain the monthly purchasing cost. He knew that nonstandard orders (for example, one requiring an overseas supplier) took more time and effort. He collected data on the number of nonstandard orders for the past 12 months and added that information to the data on purchasing cost and total number of purchase orders.

Month   Purchasing Cost   Number of Purchase Orders   Number of Nonstandard Orders
January   $18,860       370                53            
February   18,065       330                35            
March   19,250       370                61            
April   18,050       410                14            
May   19,345       400                73            
June   19,500       450                55            
July   19,670       460                30            
August   20,940       560                80            
September   19,430       440                51            
October   20,020       500                50            
November   18,800       470                12            
December   19,340       480                27            

Multiple regression was run on the above data; the coefficients shown by the regression program are:

Intercept 14,580 (rounded to the nearest dollar)
X variable 1 8.81 (rounded to the nearest cent)
X variable 2 20.37 (rounded to the nearest cent)

Required:

 

1. Construct the cost formula for the purchasing activity showing the fixed cost and the variable rate.
14,580 v + ($
8.81 v x Purchase orders)
+ ($
20.37 v x Nonstandard orders)
2. If Dohini Manufacturing Company estimates that next month will have 420 total purchase orders and 45 nonstandard orders, what is the total
estimated purchasing cost for that month? (Round your answer to the nearest dollar.)
3. What if Dohini Manufacturing wants to estimate purchasing cost for the coming year and expects 5,340 purchase orders and 580 nonstandard
orders?
What will estimated total purchasing cost be? (Round your answer to the nearest dollar.)
What is the total fixed purchasing cost?
174,960 v
Why doesn't it equal the fixed cost calculated in Requirement 2 above?
because there are 12 months in the year v
