Consider each of the following independent situations.

A. The Purchasing Department has five purchasing agents that work full time and are paid a salary of $35,000 per year. Each purchase order takes about 90 minutes, and requires approximately $5 of forms and supplies. Each order also requires, on average, about 45 minutes of telephone or Internet time to check with potential suppliers. The company pays a flat monthly rate for telephone and Internet services. The depreciation on office equipment for the Purchasing Department is $3,000 per month.

B. El Munchies, a taco stand near the college, hires counter staff at the rate of $7.50 per hour. Each staff member knows that the hours vary each week depending on the amount of business that El Munchies expects. Food is purchased from a restaurant supplier on an "as needed" basis; there is about 4 days of perishable goods inventory on hand, and a month's worth of nonperishable goods (e.g., napkins, paper cups) in inventory. Utilities are paid on a monthly basis for the previous month's usage. El Munchies has a three-year lease on the building and parking lot. Each month, the restaurant buys newspaper and radio advertising for the coming month.

C. Jared Benning runs a lawn mowing service during the summers to help pay for his college expenses. Jared bought a power mower (it runs on gasoline and must have its oil changed monthly due to the volume of lawns mowed) and a gaspowered weed eater for trimming along the edges. Jared buys a season's worth of lawn mower oil at the beginning of summer because he can get a discount if he buys in bulk. From time to time, Jared has a commitment elsewhere. When that happens, a friend of his mows the yards that day; he and the friend have agree on a per yard fee for this. Jared owns a used pickup truck and uses it to haul his equipment from job to job.
