Question

Kendra is serving two tables at the diner where she works. At the first table, the bill was $37.40, and she received 15% of the bill amount as a tip. At the second table, the bill was $34.50, and the tip was 18% of the bill amount. At which table did Kendra receive the bigger tip, and how much more did she get?

Answer 1

 

15% of 37.50 =  (15x37.50 )/100 = $5.62

18% of 34.50 =  (18x34.50)/100  = $6.21
