Final answer:
The company should keep the old equipment because the total operating costs over the next three years are $5,000 less than the total cost of purchasing and operating the new equipment, which includes a trade-in allowance.
Step-by-step explanation:
The question involves comparing the costs and benefits of keeping old manufacturing equipment versus purchasing new equipment by calculating the net change in income for a company. To determine the best financial decision, we will compare the total costs over the remaining 3-year period for both the old and new equipment.
For the old equipment, the costs would be:
- Annual operating costs: 3 years × $30,000 = $90,000
For the new equipment, the costs would be:
- Purchase price: $75,000
- Annual operating costs: 3 years × $10,000 = $30,000
- Less trade-in allowance for old equipment: $10,000
The total cost for the new equipment, therefore, is $75,000 + $30,000 - $10,000 = $95,000.
The old equipment will cost a total of $90,000 to operate for 3 more years, whereas the new equipment will have a total cost of $95,000, taking into account the trade-in allowance. As the new equipment costs $5,000 more over the 3-year period, the answer is Option A: keep the old equipment because the total net increase in income will be $5,000 if they continue to use the old equipment.
