Scattergraph, High-Low Method, and Predicting Cost for a Different Time Period from the One Used to Develop a Cost Formula Farnsworth Company has gathered data on its overhead activities and associated costs for the past 10 months. Tracy Heppler, a member of the controller's department, has convinced management that overhead costs can be better estimated and controlled if the fixed and variable components of each overhead activity are known. One such activity is receiving raw materials (unloading incoming goods, counting goods, and inspecting goods), which she believes is driven by the number of receiving orders. Ten months of data have been gathered for the receiving activity and are as follows:
Month Receiving Orders Receiving Cost
1 1,000 $18,000
2 700 15,000
3 1,500 28,000
4 1,200 17,000
5 1,300 25,000
6 1,100 21,000
7 1,600 29,000
8 1,400 24,000
9 1,700 27,000
10 900 16,000
Required:
1. On your own paper, prepare a scattergraph based on the 10 months of data. Based on this, does the relationship appear to be linear?
Yes
2. Using the high-low method, select a cost formula for the receiving activity.
Receiving cost = $6,600 + ($12 x number of receiving orders)
Using the cost formula, what is the predicted cost of receiving for a month in which 1,450 receiving orders are processed?
$ 24,000
3. Prepare a cost formula for the receiving activity for a quarter. Based on this formula, what is the predicted cost of receiving for a quarter in which 4,650 receiving orders are anticipated?
$
Prepare a cost formula for the receiving activity for a year. Based on this formula, what is the predicted cost of receiving for a year in which 18,000 receiving orders are anticipated?
