The Nanjing Company produces and sells 5,000 of baby carriages per year at a selling price of $100 each. Its current production equipment was purchased two years ago for $500,000. The equipment is being depreciated on the straight-line basis with a 5-year useful life and zero salvage value. The emergence of a new technology has led Nanjing to consider either upgrading or replacing the production equipment. The following table presents data for the two alternatives: Upgrade Replace One-time costs $300,000 $450,000 Current disposal value $60,000 N/A Variable manufacturing costs per carriage $30 $20 Remaining useful life of equipment (year) 3 3 Terminal disposal value of equipment at end of useful life $0 $0 All equipment costs will continue to be depreciated on a straight-line basis. For simplicity, ignore income taxes and the time value of money. 10. Which costs would not be relevant in determining if the company should upgrade or replace the equipment? A) $450,000 B) $60,000 C) $300,000 D) $500,000 11. Should the company upgrade or replace the equipment? A) Replace because the total relevant costs for replacing the equipment is $75,000 less than the total relevant costs for the upgrade option. B) Replace because the total relevant costs for replacing the equipment is $60,000 less than the total relevant costs for the upgrade option. C) Upgrade because the total relevant costs for upgrading the equipment is $60,000 less than the total relevant costs for the replace option. D) Upgrade because the total relevant costs for upgrading the equipment is $75,000 less than the total relevant costs for the replace option. 12. For what annual production and sales quantity would total costs for upgrading equal the total costs for replacing? A) 3,000 B) 7,000 C) 5,000 D) 2,000
