This is a very tricky problem, and 16 is indeed the correct answer. There are many words that can distract you from writing down the correct equation--you did a great job of paring away potential pitfalls in the wording. -Nathan Burke Ursula,

I never saw the quant problems like a piece of business info. For this specific problem I almost did it in my mind. I guess one tricky part is "50 percent of the trucks that were rented out during the week". If you loose the detail of the set (percent of rented during the week, not of the total), you can easily think, "ah there were 20 trucks to rent, so 50% is 10", and get the wrong answer. The second important piece of info would be: "were returned to the lot on or before Saturday morning of that week". From this two previous pieces of information you can conclude that, if there are 50% returned trucks on or before Saturday morning, then there are 50% still not returned. As the problem says that you have 12 trucks on Saturday morning, then you can infer that the 08 missing (in order to complete the original set of 20) are the 50% of the total rented trucks (R). If 0.5R=8,then R=16 16 is the greatest number of different trucks that could have been rented out during the week. Ok? Great aproach. I never saw the quant problems like a piece of business info.
