8%.
Because -> percentage change = new-old/old x 100
so 0.68/8.50 x100
Hope this helps :)
To find the percentage increase in Sara's wages, we need to compare her new hourly rate with her old hourly rate.
The formula to calculate the percentage increase is:
Percentage Increase = (New Value - Old Value) / Old Value * 100
In this case, the old value is Sara's previous wage, which is $8.50 per hour. The new value is her new wage, which is $9.18 per hour.
Let's calculate the percentage increase:
Percentage Increase = ($9.18 - $8.50) / $8.50 * 100
Simplifying the above expression:
Percentage Increase = $0.68 / $8.50 * 100
Percentage Increase ≈ 0.08 * 100
Percentage Increase ≈ 8%
Therefore, Sara's wage has increased by approximately 8%.
