Over the next few posts, I will show you many ways to solve the same word problem.
Here is the word problem:
You and some friends are going to the movies. They charge $9 for adults and $7 for children. The movie theatre had 100 customers and made $790 that night. How many of each type of ticket did they sell?
First, when working on a word problem you should ALWAYS do a setup. In this setup you explain what the variables that you are using stand for.
Examples:
t = time in seconds since program started
t = time in years since 1900
x = number of students in the class
I have seen so many students do good work but then get the answer wrong because they didn't do a setup and make sure the answer they got was what they were looking for. So, please pay careful attention to the setup in the following posts and learn how to do it well.
