Answer: The minimum amount of money that each person could have spent on snacks is $15.
Explanation:
Since we have given that
Cost of snacks each time she goes to the grocery store = $5
Cost of snacks each time he goes to the grocery store = $3
According to question, Leah and Anthony spend the same amount of money on snacks during the month of September.
So, the minimum amount of money that each person could have spent on snacks would be
L.C.M. of $5 and $3 = $15
Hence, the minimum amount of money that each person could have spent on snacks is $15.
