Question

There are 10% more boys than girls in a choir. If there are 4 more boys than girls, how many children are there altogether?

Answer 1

Explanation:

There are 10% more boys than girls in a choir.

b = 1.1g

If there are 4 more boys than girls,

b = g + 4

Replace b with 1.1g

1.1g = g + 4

1.1g - g = 4

.1g = 40

g = 4/.1

g = 40 girls, then + 4 = 44 boys
