This statement is correct as 12 is half of 24 and 2 is half of 4. We can also put this as the fraction 1/2 or 0.5 or 50% or 1:2. Therefore for every one bot there are two girls in the class.
The maximum height is 64ft and the ballon is only in the air for 2 seconds
F(3) = 2(3)+6
f(3)= 6+6
f(3)=12
Hope this helps!
