Answer 2

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 3

then add 6% 1.06* 15.3

Answer 4

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

Answer 5

you get the answer, 16.218 which rounds to 16.22

Answer 6

Answer 7
