Total number of people on boat=30
Half as many children as adults means:
Number of children = 1/2 ( Adults)
Let number of adults= A
Then equation is:
[tex]A+ \frac{1}{2}A = 30 \\
Multiply \ both \ sides \ by \ 2. \\
2A+A=60 \\
3A=60 \\
A=20 \\ [/tex]
So number of children= 1/2 x 20 =10
Answer: 10 Children
