1a The maintenance on a machine is expected to be $155 at the end of the first year, then increasing by $35 each year for the next 7 years. What sum of money would need to be set aside now to pay the maintenance for the 8-year period? Assume 6% interest.
1b. Consider again the situation in question 1a. We wish now to know the uniform annual equivalent maintenance cost. What is the equivalent A for the maintenance costs.

Calcuation of cashflows | |||||
Year 1=155 | |||||
Year 2= 155+35=190 | |||||
Year 3= 190+35=225 | |||||
Year 4=225+35= 260 | |||||
Year 5= 260+35=295 | |||||
Year 6= 295+35=330 | |||||
Year 7= 330+35=365 | |||||
Year 8= 365+35=400 | |||||
1-b) Calculation of annual equivalent maintenance cost: | |||||
EAC= Present value of cashflows/ PVAF@6% for 8 years | |||||
= 1656.97/6.2098=$266.83 | |||||
Therefore equivalent A for maintenance cost is $266.83 | |||||
