13. While cleaning your attic, you found your old rock collection. If 83.58% of the rocks have a mass of 4.7g, and the rest a mass of 2.8g, what is the average mass of your rock collection? For this problem you will need to use a process called a "weighted average." Another way to solve it is to assume you have 100 rocks.
