Q: While on vacation in New York, Greg went out for a lunch that cost $100. If sales tax in New York is 4% and he left a 6% tip, how much did Greg pay?
A: The sales tax is worth $100 x 4 / 100 = $4. Greg left $100 x 6 / 100 = $6 tip. So, the total cost for the tax and the tip is $4 + $6 = $10. Therefore, Greg paid $100 + $10 = $110 in all. The answer is 110.
