>>The price of fuel went from $1.90 to $2.25. What is the percentage 

of increase?<<

(Original price) +

      (percentage of increase expressed as a decimal)×(Original price) =

            (Final price)

Let p = the percentage of increase expressed as a decimal

              $1.90 + x·$1.90 = $2.25

                   1.9 + 1.9x = 2.25

                         1.9x = 2.25 - 1.9

                         1.9x = 0.35

                            x = 0.35/1.9 = .1842105263, approximately

              or expressed as a percent, about 18.4%
