CC should be calculated as per the following steps:
Step 1: Get the PV first, which is the initial cost of $5628.
Step 2: Get the “A” value of annual cost of $630
Step 3: Convert the “A” value to the CC1.
Step 4: Make an addition of Step 1 and Step 3.
Hence,
“A” value = Annual cost (A/F, rate, year)
= - 630 (A/F, 4%, 5)
= - 630 × 0.18463 [get the factor from compound interest table]
= - 116.3169
CC1 = “A” value / rate
= - 116.3169 / 4%
= - 116.3169 / 0.04
= - 2,907.92
Therefore,
CC = PV + CC1
= - 5628 – 2907.92
= - 8,535.92 (Answer)
