B.

Answer 1

So, the constant of proportionality must be a constant, so it cannot be a variable.

The constant of proportionality is what "rate" one increases by.

C: 25 is the answer

Answer 2

C. 25

Explanation:

The reason I say this is because if you rent this trench digger you would pay $25 an hour. This is the only answer that makes sense according to the way the questions states the numerical definitions.
