Air conditioning for a college dormitory will cost $2.8 million to install and $135,000 per year to operate at current prices. The system should last 12 years. The real cost of capital is 8%, and the college pays no taxes. What is the equivalent annual cost? (Enter your answer in dollars not in millions and round your answer to 2 decimal places.)

First, we will calculate the Net Present value of cash outflows:
| Year | Cash Flows ($) | PV Factor @8.00% | Present Value ($) | 
| 0 | 2,800,000.00 | 1.0000 | 2,800,000.00 | 
| 1 | 135,000.00 | 0.9259 | 125,000.00 | 
| 2 | 135,000.00 | 0.8573 | 115,740.74 | 
| 3 | 135,000.00 | 0.7938 | 107,167.35 | 
| 4 | 135,000.00 | 0.7350 | 99,229.03 | 
| 5 | 135,000.00 | 0.6806 | 91,878.73 | 
| 6 | 135,000.00 | 0.6302 | 85,072.90 | 
| 7 | 135,000.00 | 0.5835 | 78,771.20 | 
| 8 | 135,000.00 | 0.5403 | 72,936.30 | 
| 9 | 135,000.00 | 0.5002 | 67,533.61 | 
| 10 | 135,000.00 | 0.4632 | 62,531.12 | 
| 11 | 135,000.00 | 0.4289 | 57,899.19 | 
| 12 | 135,000.00 | 0.3971 | 53,610.36 | 
| NPV | 3,817,370.53 | 
Calculating Equivalent annual cost using the formula:

Where, NPV = $3817,370.53
r = Cost of Capital = 8%
n = no of years = 12


EAC = $ 506546.05
So, Equivalent Annual Cost = $ 506,546.05
