Calculated Answer

10

Step by Step Solution

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

n₀ =	30
n₁ =	37

(100 - n₀ - (100 - n₁)) / (100 - n₀) * 100
Evaluate 100 - n₀ = 70
(70 - (100 - n₁)) / (100 - n₀) * 100
Evaluate 100 - n₁ = 63
(70 - 63) / (100 - n₀) * 100
Evaluate 70 - 63 = 7
7 / (100 - n₀) * 100
Evaluate 100 - n₀ = 70
7 / 70 * 100
Evaluate 7 / 70 = 0.1
0.1 * 100
Evaluate 0.1 * 100 = 10
10
The answer to the problem and the result of (100 - n₀ - (100 - n₁)) / (100 - n₀) * 100 is 10
