Option b. 761,307

Step-by-step explanation:

step 1

Find the percent increase of private investigators

we know that

52,000 -----> represent 100%

so

using proportion

Find out the percent increase of (61,000-52,000=9,000) private investigators

Let

x -----> the percent increase

step 2

Find the number of police officers for a percent increase of 17.3%

we know that

648,982 ----> represent 100%

Remember that

To have a greater percent increase than that of private

investigators, the number of police officers must be greater than 761,256

therefore

The best answer is 761,307

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
