Explanation
Understanding the Problem We are given that there are initially 14 girls and 15 boys at a party. Four more boys arrive, and two girls leave. We need to find the total number of people at the party after these changes.
Calculating the New Number of Boys First, let's calculate the new number of boys. We start with 15 boys, and 4 more arrive, so the new number of boys is: 15 + 4 = 19
Calculating the New Number of Girls Next, let's calculate the new number of girls. We start with 14 girls, and 2 leave, so the new number of girls is: 14 − 2 = 12
Calculating the Total Number of People Finally, to find the total number of people at the party, we add the new number of boys and the new number of girls: 19 + 12 = 31
Final Answer Therefore, there are now 31 people at the party.
