Answer:
B)
and C) 
Step-by-step explanation:
Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.
Considering 
has a constant positive rate of slope 2.

has a constant negative rate of slope -7

The answer is $36.80
First you multiply 32 by 15 which you get $4.80
Then you just add it which you get the answer
8-3(-12x+2)
=8+-3(-12x+2)
=8+36x+-6
=36x+2
