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 201,200
Slope 365
The cost driver used was number of parts inspected.

1. What is the cost formula?
Total cost receiving of =$ + ($x)

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.

3. Using the cost formula, predict the cost of receiving for a month in which 8,000 parts are inspected.

Total cost of receiving = $

While studying for the engineering economy final exam, you and two friends find yourselves craving a fresh pizza. you can't spare the time to pick up the pizza and must have it delivered. "pick-up-sticks" offers a 1-1/4-inch-thick (including toppings), 20-inch square pizza with your choice of two toppings for $15 plus 5% sales tax and a $1.50 delivery charge (no sales tax on delivery charge). "fred's" offers the round, deep-dish sasquatch, which is 20 inches in diameter. it is 1-3/4 inches thick, includes two toppings, and costs $17.25 plus 5% sales tax and free delivery. 1. what is the problem in this situation? state it in an explicit and precise manner. 2. systematically apply the seven principles of engineering economy (pp. 3-6) to the problem you have defined in part (a). 3. assuming that your common unit of measure is dollars (i.e., cost), what is the better value for getting a pizza based on the criterion of minimizing cost per unit of volume? 4. what other criteria might be used to select which pizza to purchase?
