    75 = 15 + .05x 60 = .05x 60/ .05 = x so x = 1200 minutes

    haha yeah no kidding. that stuff on that exam was tough though. they had like little tricks that were involved. one of them involved using euler's constant to find the limit of an infinite sum. so i just made things up that weren't correct
