You can put this solution on YOUR website! 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.

You can put this solution on YOUR website! .
The complete answer is options (D) and (F).
Indeed, the correct formula for the total sales is
73n + 44(n-7)
and all its equivalent forms.
(D) is literally 73n + 44(n-7).
But if you open parentheses, you will find other equivalent form
73n + 44(n-7) = 73n + 44n - 308 = 117n - 308,
which is option (F).
Solved (correctly).

It seems it takes three responses to get the right answer....
Answers B and D are the same, and answer F is the equivalent of either B or D after parentheses are removed and like terms are combined.
