Question 1207393
i get 73n + 44(n-7).


the store gets 73 dollars a pair of shoes and 44 dollars a bag.


in one day, the store sells n pairs of shoes and (n-7) bags.


n pairs of shows * 73 dollars a pair = 73 * n. = 73n.
(n-7) bags * 44 dollars a bag = 44 * (n - 7) = 44(n-7).
the total revenue is 73 * n + 44 * (n - 7) = 73n + 44(n-7).
that's selection D.
