Yoga fun charges a $65 starting fee plus $12 per class . yoga for all charges no starting fee and $15 per class. for how many classes will the cost be the same at both places ?

Step-by-step explanation:

Yoga Fun's price is represented by 65+12c where c represents classes.

Yoga For All's price is represented by 15c where c represents classes.

We notice that for the prices to be equal, 65+12c must equal 15c. This means that we take the difference, which shows that 65 must equal 3c. We divide to determine we must take 21.666... classes for the prices to be equal.
