  1. What is the value of (−3)² − (−2)³?

    Answer: 17

    (−3)² = 9 and (−2)³ = −8; then 9 − (−8) = 9 + 8 = 17.

  2. A store marks up a product by 40% and sells it for $98. What was the original price?

    Answer: $70.00

    If the original price is p, then 1.40p = $98, so p = $98 ÷ 1.40 = $70.

  3. Which number lies between 2/3 and 3/4?

    Answer: 7/10

    2/3 ≈ 0.667 and 3/4 = 0.75; 7/10 = 0.70, which falls between them.

  4. If a population grows from 50,000 to 65,000, what is the percent increase?

    Answer: 30%

    Percent increase = (change ÷ original) × 100 = (15,000 ÷ 50,000) × 100 = 30%.

  5. Which whole number best approximates √50?

    Answer: 7

    √49 = 7 and √64 = 8; since 50 is very close to 49, √50 ≈ 7.07, so 7 is the best whole-number approximation.

  6. What is the prime factorization of 60?

    Answer: 2² × 3 × 5

    60 = 2 × 30 = 2 × 2 × 15 = 2 × 2 × 3 × 5 = 2² × 3 × 5.

  7. A worker earns $15 per hour, works 8 hours per day, and 5 days per week. How much does the worker earn in a 4-week period?

    Answer: $2,400

    Daily earnings: $15 × 8 = $120; weekly: $120 × 5 = $600; four weeks: $600 × 4 = $2,400.
