It's very difficult to determine without knowing the specifics. In other words, the distance from where you are starting from to the school, living on campus or off campus, the type of car you are driving, how many days you will actually be on campus (it's not always five days), the price of gas where you are located, distance to work if you are working, your social life, etc. Make a list of your travel needs, the total miles involved, find out how many miles to the gallon your car gets, and then you can get an approximate idea of how much to allow for gas.
About 50,000 to 65,000 Gallons
The question is best solved using basic algebra. You need 20 gallons of 32% alcohol. This will contain 0.32*20 = 6.4 gallons of pure alcohol. Now suppose you have X gallons of 25% alcohol in the mixture. That contains 0.25X gallons of pure alcohol. Also, since you have 20 gallons in total, you must have 20-X gallons of the 35% alcohol. This will contain 0.35*(20-X) = 7 - 0.35X gallons of pure alcohol. Then, the total amount of pure alcohol is 0.25X + 7 - 0.35X = 7 - 0.1X gallons. So you have 7 - 0.1X = 6.4 or 0.6 = 0.1X or X = 6. So the answer is 6 gallons of 25% alcohol and 14 gallons of the stronger stuff!
The percentage of alcohol in the solution is 3.33% (1 gallon alcohol / 30 gallons total solution = 0.0333 = 3.33%).
