Cousin's Salted Snack Company is considering two possible investments: a delivery truck or a bagging machine. The delivery truck would cost $39,987.52 and could be used to deliver an additional 48,000 bags of pretzels per year. Each bag of pretzels can be sold for a contribution margin of $0.38. The delivery truck operating expenses, excluding depreciation, are $0.52 per mile for 16,000 miles per year. The bagging machine would replace an old bagging machine, and its net investment cost would be $76,522.50. The new machine would require three fewer hours of direct labor per day. Direct labor is $15 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 19%. However, Cousin's has funds to invest in only one of the projects.
