500

Step by Step Solution

In order to solve problem, you must evaluate n₀ - n₁ / n₃ * (n₂ - n₀).

• n₀ - n₁ / n₃ * (n₂ - n₀)

• Evaluate n₁ / n₃ = 0.4

  n₀ - 0.4 * (n₂ - n₀)

• Evaluate n₂ - n₀ = 225

  n₀ - 0.4 * 225

• Evaluate 0.4 * 225 = 90

  n₀ - 90

• Evaluate n₀ - 90 = 500

  500
• The answer to the problem and the result of n₀ - n₁ / n₃ * (n₂ - n₀) is 500
