Percentage Change = (new rate - old rate) / (old rate)
New Rate = 11.5
Old Rate = 10
(11.5 - 10) / 10
1.5 / 10 = 15 / 100 = 0.15 = 15%
The percentage change in her hourly rate is 15%.
Hope this helps!
the percentage change =
( new-old / old ) x 100
(11.50-10)/10 = 0.15
0.15 x 100 = 15%
( new-old / old ) x 100
(11.50-10)/10 = 0.15
0.15 x 100 = 15%
