Hi all!
I ´m trying to have a shortcut or a starting point to solve this problem to gain more time. I ´ll appreciate any help ASAP. Many tks. Max.
Store S sold a total of 90 copies of a certain book during the last week, and it sold different numbers of copies on any two of the days. If for the seven days Store S sold the greatest number of copies con Saturday and the second greatest number of copies on Friday, did store S sell more than 11 copies con Friday?
(1) Last week Store S sold 8 copies of the book on Thursday.
(2) Last week Store S sold 38 copies of the book con Saturday.
