The percent of change will always be represented by a positive number because that change is an absolute value. Absolute values will always stay positive because the direction is ignored. It's not like a -1 or a -2, but it's a zero or a 3. Hope this helped you out! :D
Fist add 203 and 220 and you get 423. Then add all the dvds 11+3 and you get 14 then Next add all the video games 11+14 and you get 25 next divide 25 from 423 then you get 16.92 then divide the dvds 423 divided by 14 and you get 30.21
