Three people are splitting a $30 bill equally at a restaurant. What would the total tip be if they are all planning and tip the waiter 20% on their individual portion?

So since 3 divided by $30 is 10 your new question would be "What is 20% of 10?" The answer to that is 2. But since there are 3 people each giving 2 dollars then 3x2=6 so your answer is $6
