Calculated Answer

67.2

Step by Step Solution

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

n₀ =	60
n₁ =	12

n₀ * (n₁ / 100 + 1)
Evaluate n₁ / 100 = 0.12
n₀ * (0.12 + 1)
Evaluate 0.12 + 1 = 1.12
n₀ * 1.12
Evaluate n₀ * 1.12 = 67.2
67.2
The answer to the problem and the result of n₀ * (n₁ / 100 + 1) is 67.2
