 
 <prompt> ```One shady restaurant dey charge customers gratuities afta taxes without dem sabi. If my total bill na $140, the sales tax for my city na 10%, I order NY Striploin wey be $80, and I order glass of wine wey be $10, how much dem charge me for gratuities?``` <response>: ```The total bill before taxes or gratuities na $80 for the steak + $10 for the wine = $80+$10 = $90
If the tax na 10%, then the taxes wey dem pay na $90 * 10% = $9
That means say the total bill before gratuities na $90 + $9 = $99
If the final bill na $140, then dem charge you $140-$99 = $41 for gratuities

The final answer: 41.```
