Last year Jess earned $8.50 an hour at work. After a raise, she now earns $9.85 an hour. What is the percent change in her hourly wages? Round your answer to the nearest hundredth.
The percent change in Jess's hourly wages can be calculated using the following formula:
Percent change = (New value - Old value) / Old value * 100%
Plugging in the given values:
New value = 9.85
Old value = 8.50
Percent change = (9.85 - 8.50) / 8.50 * 100%
Percent change = 1.35 / 8.50 * 100%
Percent change = 0.1588 * 100%
Percent change = 15.88%
Therefore, the percent change in Jess's hourly wages is approximately 15.88%.
