Question: There are 34 kids signed up to compete in the talent show. There are 22 more girls than boys signed up to compete. How many girls are signed up to compete in the talent show?
Answer with step-by-step thinking: There are 34 kids signed up – 22 we know are girls = 12 are girls and boys. We can divide the 12 girls and boys / 2 = 6 boys are competing and 6 girls are competing. That means there are 6 + 22 = 28 girls competing.
So the answer is 28.
