Hello! The bill costed $34.62 and the tip is 15% of the total bill. To find the amount of tip to leave for the waiter, multiply the total bill by the percentage. In other words, cost * percentage (decimal form). 34.62 * 15% (0.15) is 5.193 or 5.19 when rounded to the nearest hundredth (cent). The Bell family should leave $5.19 as tips.
Note: It's important to know the formula for finding tips, because you'll need it for the future like for finding tax or percentages of things.
