Jim Jones, an industrial engineer from Tech, has improved the manufacturability of an existing product at MKBK Manufacturing Inc. in Cookeville. The improvement has resulted in a 10% reduction in processing time from 100 minutes to 90 minutes. However, the method requires an investment of $5,000. The product will be made at the rate of 4,000 for the first year and will be increased at the rate of 500 for the next three years. To justify the $5,000 investment, determine how much the reduction in processing time per hour is worth in dollars.

Exercise 2-12 cost behavior; high-low method [lo2-3, lo2-4] speedy parcel service operates a fleet of delivery trucks in a large metropolitan area. a careful study by the company’s cost analyst has determined that if a truck is driven 120,000 miles during a year, the average operating cost is 11.6 cents per mile. if a truck is driven only 80,000 miles during a year, the average operating cost increases to 13.6 cents per mile. required: 1.& 2. using the high-low method, estimate the variable and fixed cost elements of the annual cost of truck operation. (round the "variable cost per mile" to 3 decimal places.)
