Nagle Electric, Inc., of Lincoln, Nebraska, must replace a robotic Mig welder and is evaluating two alternatives. Machine A has a fixed cost for the first year of $82,000 and a variable cost of $14, with a capacity of 21,000 units per year. Machine B is slower, with a speed of one-half of A's, but the fixed cost is only $59,000. The variable cost will be higher, at $18 per unit. Each unit is expected to sell for $25. a) What is the crossover point (point of indifference) for the two machines? The crossover point for the two machines is units. (Round your response to the nearest whole number.) b) What is the range of units for which machine A is preferable? Machine A is preferable at a level of production units. (Enter your response as a whole number.) c) What is the range of units for which machine B is preferable? Machine B is preferable at a level of production units. (Enter your response as a whole number.)

"I'm not sure we should lay out $265,000 for that automated welding machine," said Jim Alder, president of the Superior Equipment Company. "That's a lot of money, and it would cost us $78,000 for software and installation, and another $40,800 per year just to maintain the thing. In addition, the manufacturer admits it would cost $41,000 more at the end of three years to replace worn-out parts." "I admit it's a lot of money," said Franci Rogers, the controller. “But you know the turnover problem we’ve had with the welding crew. This machine would replace six welders at a cost savings of $108,000 per year. And we would save another $6,900 per year in reduced material waste. When you figure that the automated welder would last for six years, I'm sure the return would be greater than our 19% required rate of return." "I'm still not convinced," countered Mr. Alder. "We can only get $14,000 scrap value out of our old welding equipment if we sell it now, and in six years the new machine will…

The annual operating costs of Machine A are $2,000. The machine will perform satisfactorily over the next five years and has an estimated market value (MV) of $3,000 at the end of its useful life. A salesperson for another company is offering a replacement, Machine B, for $14,000, with a MV of $1,400 after five years. Annual operating costs for Machine B will only be $1,500. It is believed that $10,000 could be obtained for the old machine A if it were sold now. If the before-tax MARR is 10% per year, determine whether the old machine A should be replaced by the new machine B.

Dr. Gulakowicz is an orthodontist. She estimates that adding two new chairs will increase fixed costs by $150,000, including the annual equivalent cost of the capital investment and the salary of one more technician. Each new patient is expected to bring in $3,000 per year in additional revenue, with variable costs estimated at $1,000 per patient. The two new chairs will allow Dr. Gulakowicz to expand her practice by as many as 200 patients annually. How many patients would have to be added for the new process to break even?
