  1. A worker completes a project in 6 days working alone. Another worker can complete it in 3 days alone. How many days will it take them working together?

    Answer: 2 days

    Combined rate = 1/6 + 1/3 = 1/6 + 2/6 = 3/6 = ½; time = 2 days.

  2. A bag of apples costs $3.60 and contains 12 apples. What is the cost per apple?

    Answer: $0.30

    $3.60 ÷ 12 = $0.30 per apple.

  3. If the pattern continues: 3, 6, 12, 24, ___, what is the next number?

    Answer: 48

    Each number doubles: 24 × 2 = 48.

  4. A school has 480 students. If 40% are in after-school programs, how many students are NOT in after-school programs?

    Answer: 288

    40% of 480 = 192 are in programs; 480 − 192 = 288 are not.

  5. An elevator can hold a maximum of 1,500 pounds. A group of 6 people has an average weight of 165 pounds each. Can they all ride safely?

    Answer: Yes, because 6 × 165 = 990 lbs, which is under 1,500 lbs

    6 × 165 = 990 lbs, which is safely under the 1,500-lb limit.

  6. A runner completes a 5-mile race in 40 minutes. What is her average speed in miles per hour?

    Answer: 7.5 mph

    40 minutes = 2/3 hour; 5 ÷ (2/3) = 5 × 3/2 = 7.5 mph.

  7. A store offers buy-2-get-1-free on items priced at $9 each. How much does a customer pay for 6 items?

    Answer: $36

    With buy-2-get-1-free, 6 items → pay for 4; 4 × $9 = $36.
