Answer:
The answer is B
Step-by-step explanation:
f(x) = 2x-1
f(0) = 2(0)-1
= -1
f(2) = 3
f(4) = 7
f(6) = 11
f(8) = 15
There were 151 at the morning service and 115 at the evening service<span />
Tim began with 40 comics
Further explanation:
The equation involve linear equation as there is only one object i.e. comic books
So,
Let x be the number of comic books Tim began with
Then after selling half comics Tim will have x/2 comics remaining
Now when he buys 16 more the expression will be:
![\frac{x}{2}+16](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%2B16)
He has total 36 books, then
![\frac{x}{2}+16= 36](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%2B16%3D%2036)
Subtracting 16 from both sides
![\frac{x}{2}+16-16= 36-16](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%2B16-16%3D%2036-16)
![{\frac{x}{2}}= 20\\](https://tex.z-dn.net/?f=%7B%5Cfrac%7Bx%7D%7B2%7D%7D%3D%2020%5C%5C)
Multiplying 2 on both sides
![{\frac{x}{2}}* 2= 20*2\\x=40](https://tex.z-dn.net/?f=%7B%5Cfrac%7Bx%7D%7B2%7D%7D%2A%202%3D%2020%2A2%5C%5Cx%3D40)
<u>We can recheck, if he had 40, half of them will be 20 and adding 16 makes them 36.</u>
