Back to the Problems...

Now that you've had a couple days graphing systems of linear equations, take another look at the two word problems from our blog problems Tuesday!

For each problem please do /answer the following:
1) Identify variables
2) Write equations for the word problems
3) Solve the system of equations using graphing - remember, you may have to manipulate the linear equation! (You may use your calculator or the online calcualtor to assist you.)
4) Were your original answers correct?
5) Did you find using systems of equations to be useful/helpful? Explain.
