the costs of each shown below, which should it choose? For each of the two bus models, give the relevant cost that you would use for comparison purposes. [Note: to make it easier for you to solve this problem, I have already calculated the EAA for one of the buses, as you can see. You do not need to recalcule that one.] The relevant cost for Old Reliable (to one decimal place) is: (Be careful to use the correct sign, i.e. positive or negative.) The relevant cost for Short and Sweet (to one decimal place) is: (Be careful to use the correct sign, i.e. positive or negative.)
