Question

the colorado police issued 2780 speeding tickets on the turn pike in 1999, but 2919 tickets in 2001 WHat percent increased in this?

Answer 1

(2919-2780)/2780 x 100 %

Answer 2

139/2780*100= 5%

Answer 3

This is pretty simple. Take the larger value and divide it by the smaller and subtract 100, you will have the percent.
2919/2780 = 1.05 which is 105%
if you take away 100%, you are left with 5%.
