Please help with inequalities.(Question in comments.)

OpenStudy (anonymous):

Cindy plans to join a gym. A membership cost $350. Each exercise class costs $18. She doesn't to spend more than $1000 for the year.

OpenStudy (anonymous):

Please write or help me write an inequality and please help me try to find the answer.

OpenStudy (tkhunny):

"She doesn't to spend more than $1000 for the year." It should have this in it: \(\le $1,000\)

OpenStudy (anonymous):

Oh I mean She doesn't want to.

OpenStudy (anonymous):

Still confused @tkhunny

OpenStudy (texaschic101):

350 + 18c <= 1000 (less then or equal)

OpenStudy (texaschic101):

any questions ?

OpenStudy (anonymous):

Yes. Can you help me solve the inequality?

OpenStudy (texaschic101):

sure can... do you want to try it first ?

OpenStudy (anonymous):

yes ma'am?

OpenStudy (texaschic101):

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)

OpenStudy (texaschic101):

got to go now...bye :)
