  1. A police department responded to 480 calls last month. If 40% were domestic disturbances, how many calls were domestic disturbances?

    Answer: 192

    40% of 480 = 0.40 × 480 = 192 domestic disturbance calls.

  2. An officer earns $25.00 per hour and works 40 regular hours plus 4 overtime hours at 1.5× pay. What are the officer's total earnings for the week?

    Answer: $1,150.00

    (40 × $25.00) + (4 × $25.00 × 1.5) = $1,000 + $150 = $1,150.

  3. A speed enforcement camera recorded 5 violations in the first hour, 8 in the second hour, and 3 in the third hour. What is the average number of violations per hour?

    Answer: 5

    (5 + 8 + 3) ÷ 3 = 16 ÷ 3 ≈ 5.33, which rounds to approximately 5 violations per hour.

  4. A crime prevention grant of $7,500 must be divided equally among 5 programs. How much does each program receive?

    Answer: $1,500

    $7,500 ÷ 5 programs = $1,500 per program.

  5. An officer drove 85 miles to a training location at an average speed of 50 mph. Approximately how long did the drive take?

    Answer: 1 hour 42 minutes

    85 ÷ 50 = 1.7 hours = 1 hour and 42 minutes.

  6. During a shift, Officer Kim made 3 felony arrests, 7 misdemeanor arrests, and 2 traffic arrests. What percentage of total arrests were felonies?

    Answer: 25%

    3 felony arrests ÷ (3 + 7 + 2) total = 3 ÷ 12 = 0.25 = 25%.
