Answer
A. 23
step-by-step explanation
![g(x) = {x}^{2} + 1](https://tex.z-dn.net/?f=g%28x%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%2B%201)
We put x=3 into the function g
![\implies g(3)= {3}^{2} + 1](https://tex.z-dn.net/?f=%20%20%5Cimplies%20g%283%29%3D%20%7B3%7D%5E%7B2%7D%20%2B%201)
![\implies \: g(3)=10](https://tex.z-dn.net/?f=%20%5Cimplies%20%5C%3A%20g%283%29%3D10)
Also,
![f(x)=2x +3](https://tex.z-dn.net/?f=%20f%28x%29%3D2x%20%2B3)
we substitute the value of g(3) into f
![\implies f(g(3))=f(10)](https://tex.z-dn.net/?f=%5Cimplies%20f%28g%283%29%29%3Df%2810%29)
![\implies f(g(3))=f(10) = 2(10) + 3](https://tex.z-dn.net/?f=%5Cimplies%20f%28g%283%29%29%3Df%2810%29%20%3D%202%2810%29%20%2B%203)
![\implies f(g(3))=23](https://tex.z-dn.net/?f=%5Cimplies%20f%28g%283%29%29%3D23)
8r(40)=4
r=1/80 that is the rate for each person...
10rt=7 using r we found before
10(1/80)t=7
t/8=7
t=56 minutes.
y=15
5y-20=2y+25 move terms
5y-2y = 25+20 calculate like terms
3y=45 divide both sides by 3
