Answer:
15 guests.
Explanation:
As the statement says that Carly has 9 1/2 of ice cream and each guest will be served 3/5 pint of ice cream, to determine the number of guests that she can serve, you have to divide 9 1/2 by 3/5:
9 1/2÷3/5
19/2÷3/5
=95/6= 15
According to this, the greatest number of guests that Carly can serve is 15 guests.
