Janet bought some muffins at the bakery. Each muffin is 75 cents. Janet paid $20 and got $11 in change back. How many muffins did Janet buy? Let's think first. Chain of thought:
Janet paid with $20 and got back $11, so her muffins cost $20 - $11 = $9. Each muffin cost 75 cents, so she bought 9 / .75 = 12 muffins.
Therefore, the answer is 12.
