Compute ROI Using Beginning-of-Year Asset Values: Assume the same data as in exercise 22-24, except the division uses beginning-ofyear asset values in the denominator for computing ROI.

Required:

a. Compute ROI, using net book value.

b. Compute ROI, using gross book value.

c. If you worked exercise 22-24, compare these results with those from 22-24. How different is the ROI computed using end-of-year asset values, as in 22-24, from the ROI using beginning-of-year values, as in this exercise?
