Answer:
108 boys and 81 girls
Step-by-step explanation:
If B is the number of boys and G is the number of girls, then:
B + G = 189
B − G = 27
To solve, use substitution or elimination. In this case, I recommend elimination. Add the equations together:
2B = 216
B = 108
Therefore:
G = 81
So there are 108 boys and 81 girls.
