  1. A bar chart shows monthly sales (in thousands): Jan=12, Feb=15, Mar=10, Apr=18, May=14. What is the median monthly sales value?

    Answer: 14

    Sorted values are 10, 12, 14, 15, 18 — the middle (3rd) value is 14.

  2. A store marks up items by 40% and then offers a 20% discount on the marked-up price. What is the net percentage change from the original price?

    Answer: 12% increase

    1.40 × 0.80 = 1.12, which represents a 12% net increase over the original price.

  3. A pie chart shows 5 categories. Category A covers 90°. What percentage of the total does Category A represent?

    Answer: 25%

    90° out of 360° equals 90/360 = 0.25 = 25%.

  4. The ratio of boys to girls in a class is 3:5. If there are 25 girls, how many total students are in the class?

    Answer: 40

    5 parts = 25 girls, so 1 part = 5; boys = 3 × 5 = 15; total = 15 + 25 = 40.

  5. A line graph shows a company's profit increasing from $200,000 in 2020 to $350,000 in 2024. What is the average annual increase in profit?

    Answer: $37,500

    Total increase = $150,000 over 4 years; average = $150,000 ÷ 4 = $37,500 per year.

  6. If 3x + 7 = 22, what is the value of 6x − 4?

    Answer: 26

    From 3x + 7 = 22, x = 5; then 6(5) − 4 = 30 − 4 = 26.

  7. A table shows four employees' hours worked: Ana=38, Ben=42, Carl=35, Dana=45. What is the range of hours worked?

    Answer: 10

    Range = maximum − minimum = 45 − 35 = 10.
