So Much Coffee, So Little Time: More on Caffeine in the Body and Smokin'

1 day total for the two units. This second coffee unit and "Smokin'" involve solving systems of linear equations. The first unit is a reading assignment; the second unit is worked in class. You should have covered unit 5 earlier in the semester. (It will help if you cover unit 6 before this unit, also.) Intermediate algebra or precalculus.
