The answer is 18
I hope this helps
Easy
f(g(1))
evaluate g(1) then plug thatin for x in f(x)
g(1)=(x+2)/3
g(1)=(1+2)/3
g(1)=1
f(g(1))=
f(1)=(1)^2+3(1)+6
f(1)=1+3+6
f(1)=10
f(g(1))=10
You should add -77 to 77 because it will cancel out.
3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75
D. 300 it is. is there more?
