The problem
An elementary school buys tickets for a field trip to the zoo. The number of children going on the field trip is 2 times the number of adults. Tickets for children cost $4 each and tickets for adults cost $6 each. The total cost of all of the tickets is $1650, how many tickets of each type did the school purchase? Please set up and solve this problem following the steps below:

The solver does not allow direct entry of word problems, so the best advice I can provide is that you identify relationships in the problem and translate them into equations; use variables for objects (i.e. the letter 'n' for "some integer") and numeric coefficients where quantities are known. In the end, most word problems translate to one or two equations which may then be directly entered into the software. For example, "two consecutive integers whose sum is 13" translates to "n + (n+1) = 13", which converts to n=6, giving a solution set of the integers {6, 7}.

One initial step for word problems that is quite helpful, and many times ultimately faster, is to use a search engine with your word problem encased in quotes. That type of a search may well find the problem has already been solved through one of our sources (softmath.com, algebra-answers.com, etc.). So finding an answer in such a manner would allow you to review that solution and verify that you accept it as a correct solution.
