I've been messing around with some new concepts I learned in Algebra.

It'd go something like this:

I want to work 20≤x≤30 hours per week.

I can work anytime between 7:30AM and 4:30PM

Monday through Thursday only.

BUT

I have classes on

Monday Tuesday Wednesday Thursday

8:00a to 9:15a

9:30a to 10:45a

11:00a to 12:15p

How would I go about making a system of equations based on the information provided.
