  1. A chart shows that a factory produced 120 items on Monday, 95 on Tuesday, and 110 on Wednesday. What was the average daily production?

    Answer: 108.3 items

    (120 + 95 + 110) ÷ 3 = 325 ÷ 3 ≈ 108.3 items per day.

  2. A graph shows population growth: 2000=50,000; 2010=65,000; 2020=80,000. By how many people did the population grow from 2000 to 2020?

    Answer: 30,000

    80,000 − 50,000 = 30,000 people over the 20-year period.

  3. A table lists product prices before and after a 10% discount: original price $80. What is the discounted price?

    Answer: $72

    10% of $80 is $8, so the discounted price is $80 − $8 = $72.

  4. A double bar graph compares men and women attending a community class over 3 weeks. Week 1: M=20, W=25; Week 2: M=30, W=28; Week 3: M=22, W=35. In which week did women outnumber men by the most?

    Answer: Week 3

    Week 3 shows the largest gap: 35 women vs. 22 men, a difference of 13.

  5. A map legend shows that 1 inch = 50 miles. Two cities are 3.5 inches apart on the map. What is the actual distance?

    Answer: 175 miles

    3.5 inches × 50 miles per inch = 175 miles.

  6. An electricity bill shows usage: January=850 kWh, February=920 kWh, March=780 kWh. Which month had the lowest usage?

    Answer: March

    March had the lowest usage at 780 kWh.

  7. A tally chart shows survey results: 12 people prefer coffee, 8 prefer tea, 5 prefer water, 3 prefer juice. What percentage of respondents prefer coffee?

    Total = 28; 12 ÷ 28 × 100 ≈ 43% prefer coffee.
