60

Step by Step Solution

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

• (n₁ - n₀) / n₀ * 100

• Evaluate n₁ - n₀ = 180

  180 / n₀ * 100

• Evaluate 180 / n₀ = 0.6

  0.6 * 100

• Evaluate 0.6 * 100 = 60

  60
• The answer to the problem and the result of (n₁ - n₀) / n₀ * 100 is 60
