Answer:

24 males and 7 females

Explanation:

Let's call f the number of women

Let's call m the number of men

We know that:

The drama class has a total of 31 Students

This is:


f + m = 31

We also know that:

The number of females is 17 less than the number of males. This is:


f = m-17

Now we substitute the second equation in the first


m-17 +m=31

Now let's solve the equation for m


2m-17=31


2m=31+17


2m=48


m=24

Now we substitute m in the equation and solve for f.


f=24-17\\\\f=7
