Answer:
Average investment will be $625000
Explanation:
We have given cost = $610000
And residual value = $640000
We have to calculate the average investment
We know that average investment is given by
Average investment [tex]=\frac{cost+residual\ value}{2}=\frac{610000+640000}{2}=$625000[/tex]
So the average investment will be $625000 which is used for calculating the accounting rate of return
