Estimating a cost function, high-low method. Laurie Daley is examining customer-service costs in the southern region of Capitol Products. Capitol Products has more than 200 separate electrical products that are sold with a 6-month guarantee of full repair or replacement with a new product. When a product is returned by a customer, a service report is prepared. This service report includes details of the problem and the time and cost of resolving the problem. Weekly data for the most recent 8-week period are as follows:

1 $13,700 190
2 20,900 275
3 13,000 115
4 18,800 395
5 14,000 265
6 21,500 455
7 16,900 340
8 21,000 305
