The purchase price of a natural gas fired commercial boiler (capacity=100 equivalent HP) was 5000 eight years ago. Another boiler of the same basic design, except the new boilers capacity will be 140 equivalent HP, is currently being considered for purchase. If the cost index for this type of equipment was 182 eight years ago and is 225 now, and the cost capactiy factor is o.7, what is the estimate of the purchase price of the new boiler?
