DE25-15 Write a memo to Mary Nelson comparing the costs of the Wilner and Lee jobs using the original direct labor single-allocation-base system (Daily Exercise 25-10) and the ABC system (Daily Exercise 25-14). Be sure to explain How have the costs changed under the ABC system? Why have the costs changed in the direction they changed, rather than in the opposite direction? Do the ABC results solve Nelson's puzzle from Daily Exercise 25-10? Your memo should follow the format outlined in Daily Exercise 25-12.
