Without a lot of scrutiny. I see your point, a quick glance over seems like they’re doing it the long way for some reason, almost like the extended DuPont… I’m with you, 1- (1- DLOC ) (1-DLOM) = total discount approach works best for me.
Agree. As cheesy as it may sound, it’s good that they point out there’s more than one way to skin a cat. Makes it easier on exam day with all the twists and all.
