  1. A line graph shows a student's test scores over 5 weeks: 60, 65, 70, 75, 80. If the trend continues, what score would be expected in week 6?

    Answer: 85

    The scores increase by 5 each week, so week 6 should be 80 + 5 = 85.

  2. A chart shows that 3 out of every 10 customers use a loyalty card. If 250 customers shop on Saturday, about how many would use a loyalty card?

    Answer: 75

    3/10 × 250 = 75 customers would use a loyalty card.

  3. A bar graph shows recycling by material: paper=300 lbs, plastic=180 lbs, glass=120 lbs, metal=60 lbs. What fraction of total recycling is metal?

    Answer: 1/10

    Total = 660 lbs; metal = 60 lbs; 60/660 = 1/11 ≈ 9%.

  4. A table shows commute times in minutes for 5 workers: 15, 30, 45, 20, 35. What is the range of commute times?

    Answer: 30 minutes

    Range = highest − lowest = 45 − 15 = 30 minutes.

  5. A pie chart shows a budget: 50% housing, 20% food, 15% transportation, 10% savings, 5% entertainment. If income is $2,400, how much goes to savings?

    Answer: $240

    10% of $2,400 = $240 in savings.

  6. A temperature chart shows daily highs: Mon=72°F, Tue=78°F, Wed=65°F, Thu=80°F, Fri=75°F. On how many days was the temperature above 74°F?

    Answer: 2 days

    Tuesday (78°F) and Thursday (80°F) are both above 74°F, giving 2 days.

  7. A graph shows that Company A earned $50,000 in profit and Company B earned $35,000. What is the ratio of Company A's profit to Company B's profit?
