Calculated Answer

64

Step by Step Solution

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

n₀ =	9
n₁ =	11
n₂ =	28.8

n₂ + n₂ * n₁ / n₀
Evaluate n₁ / n₀ = 1.2222222222222
n₂ + n₂ * 1.2222222222222
Evaluate n₂ * 1.2222222222222 = 35.2
n₂ + 35.2
Evaluate n₂ + 35.2 = 64
64
The answer to the problem and the result of n₂ + n₂ * n₁ / n₀ is 64
