Calculated Answer

20

Step by Step Solution

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

• (n₀ * (n₁ - n₂)) / n₂

• Evaluate n₁ - n₂ = 2

  (n₀ * 2) / n₂

• Evaluate n₀ * 2 = 160

  160 / n₂

• Evaluate 160 / n₂ = 20

  20
• The answer to the problem and the result of (n₀ * (n₁ - n₂)) / n₂ is 20
