Naomi wants to take yoga classes. She can take classes at the high school for a one-time fee of 20 dollars plus 10 dollars per class. She can join the local gym for 50 dollars and take classes for 5 dollars per class. Which statement is true about the average cost for the two options?

For six classes, the high school costs $20 + 6($10) = $80, or about $13.33 per class; the gym costs $50 + 6($5) = $80, also about $13.33 per class. For seven classes, the high school costs $90, or about $12.86 per class, while the gym costs $85, or about $12.14 per class. Therefore, the gym option costs less per class for seven classes.
