## Reflection: Real World Applications Real-life Systems 2 - Section 2: Play of the Day

I like the GOLD problem on this classwork, as it pushes students to use both algebra and a graphical representation to solve the same problem, reinforcing the idea of multiple ways to solve the same problem.

I also like this problem quite a bit, because rather than comparing two different positive rates of change, it introduces the idea of a negative rate of change, allowing students to see a different variation.
