Sasha would like to practice yoga, and is comparing the costs of two different yoga studios.

With a budget of $500, Sasha can attend 48 classes at Setting Sun Yoga than at Rising Moon Yoga.

Calculation:
Setting Sun Yoga:
$500 - $19 registration fee = $481
Each class costs $9.25
$481 / $9.25 = 52 classes

Rising Moon Yoga:
$500 - $17 registration fee = $483
Each class costs $10.50
$483 / $10.50 = 46 classes

Sasha can attend 52 classes at Setting Sun Yoga compared to 46 classes at Rising Moon Yoga.
