TRUE OR FALSE. If two investments are equal considering the time value of money, then they are said to be equivalent
For a new product, the marketing department predicts that sales are expected to be 100,000 units in year 1, increasing by 15,000 each subsequent year to 175,000 in year 6. There are 2 different manufacturing process available:
Option A: A manufacturing machine with up-front equipment purchase cost of $150,000 and the manufacturing cost per unit is $0.70. At the end of 6 years, the equipment salvage recovery is $20,000.
Option B: A machine with up-front purchase cost of $200,000 with a manufacturing cost of $0.50 per unit, and equipment salvage recovery at the end of 6 years of $40,000.
Assume an interest rate of 5% and a production period of 6 years.
Which option should you choose based on a present equivalent evaluation with no considerations for depreciation?
1. What is the present equivalent cost of Option A?
2. What is the present equivalent cost of Option B?
An equipment costing $57,500 is being considered for a production process at Dewey Chemicals. The expected benefits per year is $4,500 and estimated salvage value is $10,000. Determine the rate of return the company can get in this equipment proposal. Equipment life = 15 years.
