Nina is a small business owner who took over their family store in 2003. The store, which was originally opened in 1993, sells all types of clothes and apparel in her hometown. Later, in 2008, Nina joined Shopify as an online merchant. She began selling more products online than in her physical store. Now, many years later, Nina wants to look back on her decision to open an online shop and see exactly how much more products she has been selling.

All  products  sold in  1993 =

7032 + 5023 + 12024  + 4362  + 3540 + 5932  + 9620  =   47533

14862 + 12564  + 25463  +  2753 + 4452  +  4976  + 4062  = 69132

%  increase  between    1993  and 2003 =     [ 69132 - 47533 ] / 47533   ≈  45.4% =  45%

29086  + 25433 + 36963  + 8072  +  9833 + 7749 + 5183  =  122319

94072  + 20745 + 21945 + 21308 + 19723  + 15257  + 7243  = 200293

% increase  between  2008 and 2019 =   [ 200293 - 122319 ] / 122319  ≈  63.7%  =   65%

So sales increase  by about  65 -45 =  20%  over the two periods
