Answer:
317 is the answer.
Step-by-step explanation:
Set up the composite function and simplify.
317 is what you get.
It's a bit of a trick question. The principal square root of a real number, as indicated by the radical sign, is never negative. So if p is negative we'll get -p as the result. We write this with absolute value:

0.4(420) = 4(420)/10
(0.4 is essentially 4/10)
1680/10 = 168
There are 168 sixth graders
I think that the answer is y=-x+6
