Question

Carroll High School has a total of 94 boys and girls who play sports. If the number of boys is 9 more than four times the number of girls, how many boys play sports at this high school?

17 23 77 92



77

92

Answer 1

say a1= number of boys
a2= number of girls
a1=\[4*a2+9\]
a1+a2 =94
\[5*a2+9 = 94\]
a2=\[85/5\]
a2 =17 (number of girls)
a1 = 77 (number of boys)
