Question 993854: The average score for a class of 25 students was 75. If the 15 female students in the class averaged 70, then the male students in the class averaged:
a. 85.0
b. 70.0
c. 82.5
d. 77.5
e. 75.0
You can put this solution on YOUR website! if the average score for the 25 students was 75, then the total score for all students had to be 25 * 75 = 1875.
if the average score for the 15 female students was 70, then the total score for the female students had to be 15 * 70 = 1050.
the total score for the male students had to be 1875 - 1050 = 825.
since there were 10 male students, then their average score had to be 825 / 10 = 82.5.
