  1. A store sells 3 notebooks for $4.50. How much would 9 notebooks cost?

    Answer: $13.50

    Each notebook costs $1.50, so 9 × $1.50 = $13.50.

  2. What is the value of 7² − 3²?

    Answer: 40

    7² = 49 and 3² = 9, so 49 − 9 = 40.

  3. A recipe requires 2½ cups of flour. If you want to make 3 batches, how many cups of flour do you need?

    Answer: 7½ cups

    2½ × 3 = 5/2 × 3 = 15/2 = 7½ cups.

  4. Which number is a prime number?

    Answer: 59

    59 has no factors other than 1 and itself, making it prime.

  5. A car travels 240 miles in 4 hours. At the same speed, how far will it travel in 6 hours?

    Answer: 360 miles

    The speed is 60 mph, so in 6 hours the car travels 60 × 6 = 360 miles.

  6. What is 15% of 240?

    Answer: 36

    15% of 240 = 0.15 × 240 = 36.

  7. If n + 14 = 31, what is the value of n?

    Answer: 17

    Subtract 14 from both sides: n = 31 − 14 = 17.
