Method of Least Squares, Developing and Using the Cost Formula

The method of least squares was used to develop a cost equation to predict the cost of receiving purchased parts at a video game manufacturer. Ninety-six data points from monthly data were used for the regression. The following computer output was received:

Intercept 161,000
Slope 215

The cost driver used was number of parts inspected.

Required:

1. What is the cost formula?

Total cost of receiving = $fill in the blank 1 + ( $fill in the blank 2

Fixed cost per monthNumber of parts inspectedVariable rate

)

2. Using the cost formula from Requirement 1, identify each of the following: independent variable, dependent variable, Variable rate per professional hour, and fixed cost per month.

Independent variable

$210$147,400Number of parts inspectedTotal cost of receiving

Dependent variable

$210$147,400Number of parts inspectedTotal cost of receiving

Variable rate per professional hour

$215$161,000Number of parts inspectedTotal cost of receiving

per part inspected
Fixed cost per month

$215$161,000Number of parts inspectedTotal cost of receiving

3. Using the cost formula, predict the cost of receiving for a month in which 6,800 parts are inspected.

Total cost of receiving = $fill in the blank 8
