Student learning outcome: Solve applications of linear functions and systems of linear functions.

Sum of two numbers…

Mixture Problem:

Here is a video with a RDT problem. There are two rates, same  time. Its a lot like the problems that say “A  boat goes upstream in the same time it goes downstream….. ”  Or “the plane travels with the wind and against the wind”…. At the end of the video I say “the rate of the kid off the sidewalk and that’s not what I mean to say. I should have said the rate of the kid on a still sidewalk”.
