The article states that, at its highest, the annual expenditure was about 420M, so this is nearly a 25% cut in spending. Florida also ranks 49th in spending for mental health services [1], spending less than 1/3 annually per person than the average state. They also have the third highest percentage of mentally ill and uninsured people in the country.

To put this in perspective, Florida spent over $2.2B on its corrections system in 2014 [2].
