Gas prices

Last month the equation would be 350/23 x 2.43=36.98



This month with gas at 1.93 I would spend 350/23 x 1.93=29.36 per week.



So 36.98-29.36=7.62 in savings!

Polynomials

Something new i've learned is that a term with no variables is called a constant term. Something that is now clearer is that unlike terms can be multipilied but not added or subtracted.
