Calculated Answer

85

Step by Step Solution

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

n₀ =	1
n₁ =	17
n₂ =	80

n₁ * n₂ / (n₁ - n₀)
Evaluate n₁ - n₀ = 16
n₁ * n₂ / 16
Evaluate n₂ / 16 = 5
n₁ * 5
Evaluate n₁ * 5 = 85
85
The answer to the problem and the result of n₁ * n₂ / (n₁ - n₀) is 85
