Question 325
<pre>>>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%
