Question

John receives a bill of $42.40 for his dinner what amount of money should he give as a tip if he wants to exactly 15% of the bill

Answer 1

Answer: $6.36

Take 42.40

To find 10% move the decimal point to the right

4.240

Take away the 0

4.24 is 10%

half of 10 is 5 so half 4.24

2.12

10 + 5 is 15 so add them

4.24 + 2.12 =

6.36
