In 1930, the average cost for a gallon of gasoline was $0.25. in 2007, the average cost for a gallon of gasoline is $2.60. what is the percent of increase rounded to the nearest whole number

Answer 1

Original price=$0.25
New price=$2.60
Change in value=new price-original price
Change in value=2.60-0.25
Change in value=2.35
%increased=change in value/original value x 100%
%increased=2.35/0.25x100
%increased=940%
