Calculated Answer

100

Step by Step Solution

In order to solve problem, you must evaluate (n₂ * (1 + n₀)) / n₁.

n₀ =	3
n₁ =	7
n₂ =	175
n₃ =	7

(n₂ * (1 + n₀)) / n₁
Evaluate 1 + n₀ = 4
(n₂ * 4) / n₁
Evaluate n₂ * 4 = 700
700 / n₁
Evaluate 700 / n₁ = 100
100
The answer to the problem and the result of (n₂ * (1 + n₀)) / n₁ is 100
