Answer:
[tex]375001[/tex] police officers
Step-by-step explanation:
[tex]\frac{30,000}{25,000} = \frac{30}{25} = \frac{120}{100} = 1.2[/tex]
That's a 20% increase.
So increase the police by 20% gets you:
[tex]312500 * 1.2 = 375000[/tex]
Based on the wording of the question, if you want a greater percentage, the answer should be a single policeman more, thus 375,001.
