John makes $ a week from his job. He earns a raise and now makes $ a week. What is the % increase?

Calculated Answer

60

Step by Step Solution

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

n₀ =	50
n₁ =	80

(n₁ - n₀) / n₀ * 100
Evaluate n₁ - n₀ = 30
30 / n₀ * 100
Evaluate 30 / n₀ = 0.6
0.6 * 100
Evaluate 0.6 * 100 = 60
60
The answer to the problem and the result of (n₁ - n₀) / n₀ * 100 is 60
