Question: 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.
| Intercept | 205,400 |
| Slope | 405 |
The cost driver used was number of parts inspected.
Required:
1. What is the cost formula?
Total cost of receiving = $ + ( $ Number of parts inspected )
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 | Number of parts inspected | |
| Dependent variable | Total cost of receiving | |
| Variable rate per professional hour | $405 | per part inspected |
| Fixed cost per month | $205,400 |
3. Using the cost formula, predict the cost of receiving for a month in which 7,200 parts are inspected.
Total cost of receiving = $
