Answer:
The 2nd and last options.
Step-by-step explanation:
By looking at the table we know that the 2nd one is an answer for sure.
Also by looking at the table we know that the 3rd and 4th are not true.
put in -1/2 in the function to see if you get -2
1/2(-1/2)+3/2
-1/4+3/2
-1/4+6/4
5/4
So The first one doesn't work either.
Now the last one:
1/2(4)+3/2
4/2+3/2
7/2
So the last one works too.
Hope this helps :)

Answer:
At mile 3 company A will start charging less.
Step-by-step explanation:
I came to this conclusion by realizing that no matter what company A will always charge $107 so, in theory all we needed to do was get company eight to $108.
