\[12x+18y \le 80\]

oops, sorry i missed the parking fee!

OpenStudy (anonymous):

looks good to me!

OpenStudy (anonymous):

either is fine but technically it should be \[0 \le x \le 7\] and similarly for y.

OpenStudy (anonymous):

i assume they all can drive...

OpenStudy (anonymous):

i would ignore the unaddressed issues in the problem... can everyone drive is Nathan a student etc.

OpenStudy (anonymous):

no, the equal parts should be in there. like you had previously... \[12x+18y\le72\]\[x+y\le7\]\[0\le x\le7\]\[0\le y \le7\]
