Answer: Cost of keeping old machine is $469,000
Cost of Purchasing New Machine is $271,000
Explanation:
Keeping the old machine.
When calculating the cost of keeping the machine you use the disposal value.
Cost = (Disposal Value - Residual Value) + Total Operating Costs for remaining lifetime
Cost = ( 88,000 - 15,000) + ( 36,000 * 11 years)
Cost = 73,000 + 396,000
Cost = $469,000
Cost of keeping old machine is $469,000.
Cost of New machine
Cost = (Disposal Value - Residual Value) + Total Operating Costs for remaining lifetime
Cost = (239,000 - 76,000) + (12,000 * 9)
Cost = 163,000 + 108,000
Cost = $271,000
Cost if New machine purchased,
= $271,000
