To find this out we first need to find the total number of packs of cards that Sara bought at the two stores combined. When we add them we get a total number of 11. Because each pack of cards has 17 cards inside, we can multiply 11 (the total number of packs that she bought) and 17 ( the number of cards in a pack). When we do this we find the total number of cards that she bought was 187.
