## Brainteaser answer

Billie bought the sneakers for $100.

Then they increased the price by 50%, which is $50, making the new price $150.

Next they reduced the price by 50%. And 50% of $150 is $75, so the sneakers sold for $75.

Overall, Billie bought the sneakers for $100 and sold them for $75, so they lost $25.
