Answer:
Train got a raise of 16%
Step-by-step explanation:
To find this, start by taking the equation for percent change
(New - Old)/Old * 100 = % Change
Now plug in known values
(580 - 500)/(500) * 100 = % change
80/500 * 100 = % change
.16 * 100 = % change
16 = % change
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.
