Calculated Answer

19.55

Step by Step Solution

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

n₀ =	15
n₁ =	23.00

n₁ - n₁ * n₀ / 100
Evaluate n₀ / 100 = 0.15
n₁ - n₁ * 0.15
Evaluate n₁ * 0.15 = 3.45
n₁ - 3.45
Evaluate n₁ - 3.45 = 19.55
19.55
The answer to the problem and the result of n₁ - n₁ * n₀ / 100 is 19.55
