Answer 1

The least possible number of times that Miranda has been to the store is 9.

Explanation:

The lowest common factor of $7 and $9 is $63. To get the number of times Miranda has been to the store, you divide the total amount of money spent, $63, by the increase per visit, $7, to get at least 9 visits to the store.
