For every 2 adults, there are 3 boys and 5 girls. We group them together.
2 adults x $6 = $12
3 boys x $5 = $15
5 girls x $4 = $20
Total for above = $12 + $15 + $20
= $47
So 1 group of people gets $47.
5 - 3 = 2
And for every group, there are 2 more girls than boys.
$705 ÷ $47 = 15
There are 15 of such groups.
2 x 15 = 30
So for 15 groups, there are 30 more girls than boys in total.
2 adults x $6 = $12
3 boys x $5 = $15
5 girls x $4 = $20
Total for above = $12 + $15 + $20
= $47
So 1 group of people gets $47.
5 - 3 = 2
And for every group, there are 2 more girls than boys.
