# Estimate amount of money needed for a 15% tip

Here is the question: Suppose that you want to leave your server a 15% tip on the dinner bill. The total bill amounts to \$24.19. Estimate the amount of money that you should leave for a 25% tip.

The professor wants an estimate only and no exact answer.

I am having troubles starting the problem. I tend to answer the problem and not estimate what that answer could be. I am not sure if I should round the bill amount down or just leave it as the questions says.
