A city police force is made up of 24% females. If there are 72 females on the force, how many males are on the force?

erastovalidia [21]

Answer:

228 males

Step-by-step explanation:

Let x be the number of males.

This means x + 72 is the total number of people.

So $\frac{72}{x+72}$ is the fraction of females in the force.

Thus, we can form the equation:

$\frac{72}{x+72} = 0.24$

$x+72 = \frac{72}{0.24}$

$x = \frac{72}{0.24} -72$

$x = 228$

Thus, the answer is 228 males.
