Answer:
$7,986
Step-by-step explanation:
To calculate the equivalent annual cost for 5 year period at an interest rate of 10% per year we need to go through some minor calculations first.
DATA
Cost in first year (A) = $10,000
Decrease in cost each year after the first year (G) = $560
Interest rate = 10%
Time period = 5 years
Solution
EAC = A - G (A/G, i, n)
EAC = $9,000 - $560(A/G, 10%, 5)
EAC = $9,000 - ($560 * 1.8101)
EAC = $9,000 - $1,013.656
EAC = $7,986
