Based on the following information:

Government water resource specialists have estimated that the Great Lakes currently contain about 200 thousand tons of pesticide pollutants, the amount of new pesticide pollutants that enter the lakes are about 20 thousand tons per year, and the stock of pesticide pollutants was about 200 thousand tons last year.

The answer for the quesiton: Based on this information, what is the stock dissipation rate?

Is:

C) 10 percent

Explanation:

The reason behind this is very simple, we need to discover the percentage of the increase per year. We have that the total number is 200 thousand tons. The quantity of yearly increase is 20 thousand tons per year. We need to execute the following operation 20 x 100 divided by 200 and we obtain the answer: c or 10 percent. Because we use the 20 as a base to multiply it for our 100 percent and divide it in the total mount.
