Good morning!
Please can you kindly advise how to identify when to use the annuity factor v.s when to use the formula (1+r^x)?
In the following example, the solution multiplies the cost by the annuity factor to find the present value, but goes on to divide the scrap value by (1+r^3), to get the present value please can you help me understand why 2 different methods are used here, and how to know when to use which method?
Example:
A machine will initially cost $540,000, have a life of 3 years, scrap value of $120,000 and annual running costs of $47,000. Cost of capital is 10% – assume all cash flows except the initial cost occur at the end of the relevant year. What is the equivalent annual cost of the machine?
Solution:
Negative NPV ($’000) = ($540 + $47 x 2.487) – ($120 ÷ 1.10^3) = $566.731
Equivalent annual cost = $566.731 ÷ 2.487 = $227.875
Therefore answer = $228,000 to the nearest $’000.Thank you very much in advance!

I do suggest that you watch my free Paper MA lectures on investment appraisal, because this is revision from Paper MA.
