Gateway Tours is choosing between two bus models, one of which lasts longer than the other. Gateway's discount rate is 8%. It plans to continue with one of the two models for the foreseeable future. Based on 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 recalculate 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.)
