Original: 35
\New: 40
\Since the new amount is greater than the original, this is a percent of increase.
\The amount of change = New amount– Original amount.

Let r be the percentage of increase.
\Use the original number, 35 as the base.
\The percent proportion is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=20afc5195c76828a9491fe81b821f779.png\")

To solve for r, first find the cross products.
