Answer:
65.75% change
Step-by-step explanation:
Equation for percent change
(|x2-x1| / x1) * 100%
48 million / 73 million * 100% = 65.75% decrease
First, we solve to find out what percent of the population has brown eyes and black hair. There are 303 people total, and 64 people with the description. After dividing, we find that about 21% of people have black hair and brown eyes.
Next, we use the chart to see that 9 out of the total 303 people have black hair and blue eyes. We divide this and see that this is only about 3%.
Last, we subtract 3 from 21 and get 18%
So, the answer is 18%
