The dinner bill at Chillis Restaurant was $23.33, and you leave a tip of $3.50. What percentage did you tip?

15%

Step-by-step explanation:

the percentage is equal to (tip/bill) * 100

(3.50 / 23.33) * 100 = 15%

15%

Step-by-step explanation:

2.33 is  10% of 23.33 (move the decimal one place to the left)

1.17 is 5% of 2.33 (5% is half of 10%, so divide by 2)

2.33 + 1.17 = 3.50
