Strahn Foods Inc. is considering two possible investments: a delivery truck or a bagging machine. The delivery truck would cost $66,523.56 and could be used to deliver an additional 49,000 bags of taquitos chips per year. Each bag of chips can be sold for a contribution margin of $0.38. The delivery truck operating expenses, excluding depreciation, are $0.52 per mile for 17,000 miles per year. The bagging machine would replace an old bagging machine, and its net investment cost would be $43,192.50. The new machine would require three fewer hours of direct labor per day. Direct labor is $10 per hour. There are 250 operating days in the year. Both the truck and the bagging machine are estimated to have nine-year lives. The minimum rate of return is 9%. However, Strahn Foods has funds to invest in only one of the projects.
