Answer:

The answer is D. k=5

Step-by-step explanation:

The constant of proportionality is just the rate the x increases or decreases at.  The x is increasing by 5 over time so the COP or rate is 5.

Answer:

The answer is D: K=5

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

So, what you do is that you get the first number, which is 5/25. Simplify it and divided to get it as low as possible, if you do that, you would get 1/5 and 1/5 can also mean 5/1 in these situations. So your basic answer is 5.
