Total of 92 students in the school band. There are 16 more girls than boys in the band. How many girls are in the band?
4 answers
76 girls
Alex is wrong.
Let x = the number of girls
x + x + 16 = 92
2x + 16 = 92
2x = 92 + 16
2x = 108
x = 54
Let x = the number of girls
x + x + 16 = 92
2x + 16 = 92
2x = 92 + 16
2x = 108
x = 54
But 54 and 16 doesnt equal 92
Ms Sue probably meant to say
let x = the number of boys
then x+16 is the number of girls
x + x+16 = 92
2x = 92-16
2x=76
x = 38
the number of boys is 38
the number of girls is 54
check:
do they add up to 92 ? YES
are there 16 more girls than boys ? YES
