Kaylee got a 15% raise. She now earns $23 an hour. How much did she earn before the raise?
1.15x = 23
x = ?
1.15*0.05=23
To find out how much Kaylee earned before the raise, we can use the formula for calculating a percentage increase.
Let's denote Kaylee's original salary as "x".
Since she received a 15% raise, her new salary is 15% more than her original salary. Mathematically, we can express this as:
x + 0.15x = $23
To simplify this equation, we combine the two terms on the left side:
1.15x = $23
Now, we need to isolate x by dividing both sides of the equation by 1.15:
x = $23 / 1.15
Evaluating the right side of the equation gives us:
x ≈ $20
Therefore, Kaylee was earning approximately $20 per hour before the raise.
