Calculated Answer

63

Step by Step Solution

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

n₀ =	18
n₁ =	7
n₂ =	9

n₁ * n₀ / (n₂ - n₁)
Evaluate n₂ - n₁ = 2
n₁ * n₀ / 2
Evaluate n₀ / 2 = 9
n₁ * 9
Evaluate n₁ * 9 = 63
63
The answer to the problem and the result of n₁ * n₀ / (n₂ - n₁) is 63
