(I seem to be stuck on the simple algebra here)... e.g. 2011, toy was £5, 2012, toy is £10. What is the percentage increase? So, (10-5)/5 = 1 (i.e. 100% increase), AND, (10/5)-1 = 1 (i.e. also 100% increase). Thanks in advance.Answered by Penny Nom.     Annual percent growth 2008-12-13 From Joe:If Wall-Mart had sales of \$58,200,000,000 in the year 2002 and \$90,800,000,000 in the year 2006. 1. Find what percent that increase is of the 2002 sales? I came up with (9.08*10^10 - 5.82*10^10) / 5.82*10^10 * 100 = 56.01% increase. Is this correct? 2. What was the percent GROWTH in Wal-Mart's sales from 2002-2006? I am having trouble figuring out how to do the Growth problem. I would appreciate any help.Answered by Harley Weston.
