Members at a yodeling school pay $10 per class plus an annual $100 membership fee. Non-members pay $15 per class. If you plan on taking 25 classes a year, is it worth the $100 investment to become a member? Show your thinking and be sure to define any variables used.
Well if you are a non member, you will pay $375 for the 25 classes. If you are a member you end up only paying $300. You spend 100 up front but pay $75 less in the end
