Explanation

Company E units sold in 2006: 1.4 (hundred). Company E units sold in 2007: 1.7 (hundred). Increase = (1.7 - 1.4) / 1.4 = 0.3 / 1.4 = 3/14 = 21.42%.

AI explanation

Company E sold 1.4 hundred units in 2006 and 1.7 hundred units in 2007. The percentage increase formula is the difference between the two values divided by the original value, all multiplied by 100. The calculation is ((1.7 - 1.4) / 1.4) multiplied by 100, which gives approximately 21 percent.
