  1. A store sold 120 items in January, 150 in February, and 90 in March. What was the average number of items sold per month?

    Answer: 120

    The average is calculated by adding all values (120+150+90=360) and dividing by the number of months (360÷3=120).

  2. A pie chart shows that 25% of a $2,000 budget is spent on food. How much money is spent on food?

    Answer: $500

    25% of $2,000 equals $500 (0.25 × 2,000 = 500).

  3. A bar graph shows monthly rainfall in inches: January=3, February=2, March=5, April=4. What is the total rainfall for all four months?

    Answer: 14 inches

    Adding all monthly values: 3+2+5+4=14 inches total.

  4. A table shows test scores for 5 students: 72, 85, 91, 68, 84. What is the median score?

    Answer: 84

    When sorted in order (68, 72, 84, 85, 91), the middle value is 84, which is the median.

  5. A company's profit was $10,000 in 2020. It increased by 20% in 2021, then decreased by 10% in 2022. What was the profit in 2022?

    Answer: $10,800

    $10,000 × 1.20 = $12,000 in 2021; then $12,000 × 0.90 = $10,800 in 2022.

  6. An employee worked the following hours: Monday=8, Tuesday=7, Wednesday=9, Thursday=8, Friday=6. If the hourly wage is $15, how much did the employee earn that week?

    Answer: $570

    Total hours = 8+7+9+8+6 = 38 hours; 38 × $15 = $570.

  7. A chart shows 200 survey respondents: 30% prefer Brand A, 45% prefer Brand B, and 25% prefer Brand C. How many people prefer Brand B?

    Answer: 90

    45% of 200 respondents = 0.45 × 200 = 90 people prefer Brand B.
