Dr. Jones is interested in expanding his practice by adding a piece of radiology equipment. The basic cost of the equipment woul

inysia [295]

Answer:

<u>Dr. Jones' projected income is US$ 56.793, projected costs are US$ 61,935.48 and projected loss is US$ 5,142.48 for the 1st year of the radiology service.</u>

Step-by-step explanation:

1. Dr. Jones Income per year:

Income = 1,100 * 51.63

<u>Income = US$ 56,793</u>

<u>2. Dr. Jones Costs</u>

Equipment = US$ 1,564.29 loan cost monthly

Radiology tech salary = US$ 39,600 (including taxes and fringe benefits)

Variable cost = US$ 3.24 * 1,100

Equipment = 1,564.29 * 12 = US$ 18,771.48

Radiology tech salary = US$ 39,600

Variable cost = US$ 3,564

Total costs = Equipment loan cost + Radiology tech salary + Variable cost

Total costs = 18,771.48 + 39,600 + 3,564

<u>Total costs = US$ 61,935.48</u>

<u>3. Dr. Jones Profit or Loss</u>

Profit or loss = Income - costs

Profit or loss = 56,793 - 61,935.48 (Costs are higher than income)

<u>Loss = US$ 5,142.48</u>
