%change=100(final-initial)/initial

%change=100(3.1-3.35)/3.35= -7.5%

Always find the difference in prices first.

3.45 - 3.20 = $.25 difference


Always divide the difference by the original price. Change this number into a per cent.

.25/3.45 = .07246 = 7.2% decrease <==ANSWER


I hope that helps!! :-)
