To find the minimum, find the minimum, equivalent uniform annual cost, that is euac, equivalent uniform annual cost, that is euac.
00:45
We need to calculate the annual cost and the present worth of these costs.
00:49
So the annual cost include depreciation repairs and the cost of capital.
00:54
First we have to calculate the depreciation.
01:05
The machine's market value declines by 20 % annually from its previous year's market value.
01:11
So this is an arithmetic declining series.
01:14
The formula to calculate the annual depreciation is depreciation equals initial cost minus salvage value divided by n.
01:41
So given initial cost equals $2 .10, salvage value is zero.
01:51
Because assuming the machine has no residue value, and n is the economic life of the machine.
02:03
So initial cost, $10 ,000, minus initial cost would be equals to $10 ,000.
02:41
Salvage value is zero, economic life of the machine.
03:02
So since the economic life of the machine is not provided, so we cannot calculate the minimum euac or to determine the economic life...
