Answer:
$308,500.85
Explanation:
$181,000 eight years ago in real dollars was $181,000 / 162 = $111,728.40
new boiler with a 1.42X capacity x capacity factor = 1.42 x 0.8 = 1.136 (the price of the new boiler is 1.136 times the old boiler)
current price of the new boiler in real dollars = 1.136 x $111,728.40 = $126,923.46
real dollars converted to current nominal dollars = $126,923.46 x 2.21 = $280,500.85
price of the new boiler + additional optional features = $280,500.85 + $28,000 = $308,500.85
