Carla = 5 years old
Jim = 2 years old
Peter = 15 years old
(Peter was 14 years old one year ago)
5+2=7
7x2=14 (14 is the age from one year ago meaning 15 is the current age)
15-2=13
When you see % next to a number, you multiply it by .01.
10 becomes .1
10.5 becomes .105
220*.1=22, so this is the 10% off
220*.105=23.1, so this is the 10.5% service charge.
220-22+23.1=$221.10 for the ticket.
