Answer:
The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.
Step-by-step explanation:
From the random sample, we can expect that 
of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect 
students to have played on a sports team that year.
The original equation: 8(5.95)+8(4)+8(3.60)+8(2.25)= $126.4
To answer the question you should add all of the numbers within the parenthesis together: 5.95+4+3.60+2.25= $15.8
Then multiply that answer times the total number of people: 8(15.8)= $126.4
