3 friends went to dinner and their total bill was $19.50. They each brought $8. If a tip is typically between 15% and 20% of the bill do they have enough for dinner and tip?

15% tip:
19.50 * 1.15 = 22.43

20% tip:
19.50 * 1.2 = 23.4

3 friends each brought $8, so they have:
3 * 8 = $24

So the $24 will cover both a 15% tip and a 20% tip
