Are there answer choices ??
Yea umm
A. 6.25%
B. 8.75%
C.62.5%
D.87.5%
hours increase = 40 - 15 = 25
% increase = (25/15)*100 = ?
actual increase: 40-15 = 25
% increase: 25/15 = 5/3
so that's factor of 2.67 or a 167% increase
To find the percentage increase in the hours Mrs. Copeland works, we need to calculate the difference between her current weekly hours and her previous weekly hours, and then express that difference as a percentage of her previous weekly hours.
First, let's calculate the increase in hours:
Current weekly hours = 40 hours
Previous weekly hours = 15 hours
Increase = Current weekly hours - Previous weekly hours
Increase = 40 hours - 15 hours
Increase = 25 hours
Now, let's calculate the percentage increase:
Percentage Increase = (Increase / Previous weekly hours) * 100
Percentage Increase = (25 hours / 15 hours) * 100
Percentage Increase = 1.6667 * 100
Percentage Increase ≈ 166.67%
Therefore, the hours Mrs. Copeland works increased by approximately 166.67%.
