Today's lesson (pdf) was a first look at solving Systems of Equations by Substitution through the lens of iPhone rate plans. We'll spend some more time with this on Wednesday.

Tonight's homework is:

- Complete Step 8 of the lesson (pdf), which is solving this system by substitution:

y = 59.99

y = 39.99 + .45(x - 450)

So, solve 59.99 = 39.99 + .45(x - 450)

The first thing we do on Wednesday will be this problem - make sure you've completed it - and can complete it again from the start.

- Complete the Solving Systems of Equations by Graphing Online Pre-Assessment.

- Do you need to re-assess on your midterm? If so, make an appointment and come in for help and/or to re-assess.
