Calculated Answer

600

Step by Step Solution

In order to solve problem, you must evaluate n₁ / (n₀ / 100 + 1).

n₀ =	10
n₁ =	660

n₁ / (n₀ / 100 + 1)
Evaluate n₀ / 100 = 0.1
n₁ / (0.1 + 1)
Evaluate 0.1 + 1 = 1.1
n₁ / 1.1
Evaluate n₁ / 1.1 = 600
600
The answer to the problem and the result of n₁ / (n₀ / 100 + 1) is 600
