The increase in price is 140% of the original price. The original price was 100% of the original price since 100% is a whole quantity. Now the new price is 140% more than it was, so the new price is 100% + 140% of the old price. 100% + 140% = 240%
Now we find 240% of $50. To find a percent of a number, multiply the percent by the number.
240% of $50 = = 240% * $50 = 2.4 * $50 = $120
