Donavan Wallace · Answer 1

3 packages of cups 4 packages of napkins

Step-by-step explanation:

You need at least enough for 60, so any requirement for a partial package means you need to buy another whole package. The "ceiling" function gives the next higher integer for a non-integer value.

cups = ceiling ((60 cups) / (24 cups/package)) = ceiling (2.5) packages

= 3 packages

__

napkins = ceiling ((60 napkins) / (18 napkins/package))

= ceiling (3 1/3) packages = 4 packages
