Answer:
1 bubble: 60 people, Yes Voucher bubble: 33, No Voucher bubble: 27 people, Boy yes bubble: 20, girl yes bubble: 13, boy no bubble: 18, girl no bubble: 9
Explanation:
When you get to the third statement do 27=3x
9=x
x represents amount of girls who do not have their voucher
18 boys didn't have their voucher
subtact 18 from 38 to find the amount of boys who had their voucher. And then subtract 9 from 22 to find the amount of girls who had their voucher.
