If there are 27 students in class and 7 girls are more than boys. How many total girls are in class?
- 10
- 19
- 14
- 17
Explanation
Total students = 27
Since 7 more girls than boys, let's represent the number of boys as x.
Number of girls = x + 7
Total students = Boys + Girls
27 = x + (x + 7)
Combine like terms:
27 = 2x + 7
Subtract 7:
20 = 2x
Divide by 2:
10 = x
Number of boys = 10
Number of girls = 10 + 7 = 17
Therefore:
Total girls in the class = 17
