Answer
81 bees

The correct answer is 81 bees — So the hive has about 81 bees after 10 days.

Step-by-step solution

  1. Initial number of bees = 50.
  2. Daily increase factor = 1 + 5 % = 1.05.
  3. After 10 days: 50 × (1.05)^10.
  4. Compute (1.05)^10 ≈ 1.62889.
  5. Multiply: 50 × 1.62889 ≈ 81.44.
  6. Round to nearest whole number: 81 bees.
  7. So the hive has about 81 bees after 10 days.
Common mistake: Adding 5 % each day instead of multiplying

Concept tested: Compound population growth
