i did it all in my head lol

Answer 8

yes it means 18 - 0.15*18

15% is how much people tip, and you can do it in your head.
10% of 18 is 1.8
half of 1.8 (5%) is .9
1.8+.9= 2.70
take that off 18

Answer 9

then you get 15.3

Answer 10

then add 6%
1.06* 15.3

Answer 11

notice 1.06 * 15.3 is the same as 15.3 + 0.06*15.3
