Dr. Jones is interested in expanding his practice by adding a piece of radiology equipment. The basic cost of the equipment would be $79,000 for the first year.

Additionally, Dr. Jones must factor in the cost to hire a radiology tech with a predicted $39,600 annual salary (this includes all taxes and fringe benefits). The office already has a radiology room, so there are no fixed costs associated with this purchase. You help Dr. Jones determine that the office will do 1100 studies per year with an average reimbursement of $51.63. The variable cost per study is $3.24.
