Rapid Delivery Inc. operates a parcel delivery service across the nation. The company keeps detailed records relating to operating costs of trucks
and has found that if a truck is driven 150000 miles per year the average operating cost is 10 cents per mile. This cost increases to 11 cents per mile if
a truck is driven only 100000 miles per year.
Assume that all of the activity levels mentioned in this problem are within the relevant range.
a. Using the high-low method derive the cost formula for truck operating costs.
b. Using the cost formula you derived above what total cost would you expect the company to incur in connection with the truck if it is driven 130000
miles in a year?
