Step by Step Solution

In order to solve problem, you must evaluate n₂ / ((n₀ / 100 + 1) * (1 - n₁ / 100)).

• n₂ / ((n₀ / 100 + 1) * (1 - n₁ / 100))

• Evaluate n₀ / 100 = 0.1

  n₂ / ((0.1 + 1) * (1 - n₁ / 100))

• Evaluate 0.1 + 1 = 1.1

  n₂ / (1.1 * (1 - n₁ / 100))

• Evaluate n₁ / 100 = 0.05

  n₂ / (1.1 * (1 - 0.05))

• Evaluate 1 - 0.05 = 0.95

  n₂ / (1.1 * 0.95)

• Evaluate 1.1 * 0.95 = 1.045

  n₂ / 1.045

• Evaluate n₂ / 1.045 = 5000

  5000
• The answer to the problem and the result of n₂ / ((n₀ / 100 + 1) * (1 - n₁ / 100)) is 5000
