Question

The purchase price of a natural gas-fired commercial boiler (capacity X) was $180,000 eight years ago. Another boiler of the same basic design, except with capacity 1.45X, is currently being considered for purchase. If it is purchased, some optional features presently costing$30,000 would be added for your application. If the cost index was 165 for this type of equipment when the capacity X boiler was purchased and is 220 now, and the applicable cost capacity factor is 0.75, what is your estimate of the purchase price for the new boiler?
