Question

A drama class has a total of 27 students. The number of females is 7 less than the number of males. How many males and how many females are in the class?

Answer 1

17 males, 10 females

Explanation:

Let f be the number of females and m be the number of males.

f + m = 27

f = m - 7, so m - 7 + m = 27

2m - 7 = 27

2m = 34

m = 17, f = 10
