you solve it pretty much like you do an equation. Can you try to solve it first ? Or do you just want me to
OpenStudy (texaschic101):
ok...I am not gonna be on much longer, so here it is....
350 + 18c <= 1000
18c <= 1000 - 350
18c <= 650
c <= 650/18
c <= 36.11 rounds to 36
she can join and take, at most, 35 exercise classes and be within her budget.
OpenStudy (texaschic101):
oops...at most 36 exercise classes
OpenStudy (texaschic101):
we can even check it...
350 + 18(36) <= 1000
350 + 648 <= 1000
998 <= 1000 (correct)
