Question

A problem states: "There are 5 more girls than boys at the party. There are 27 children at the party in all. How many boys are there at the party?"

Let b represent the number of boys.

Which expression represents the number of girls?
A .b+5 B. b*5 C. b-5 D. 5-b

Answer 1

if b = boys......and there are 5 more girls then boys.....then the expression that represents girls is : b + 5

b + b + 5 = 27
2b + 5 = 27
2b = 27 - 5
2b = 22
b = 22/2
b = 11......there are 11 boys

g = b + 5
g = 11 + 5
g = 16....there are 16 girls

Answer 2

27-5 = 22

22/11 = 11

there are 11 boys at the party

expression = b+5
