Sixty people are invited to a party. there are 24 cup in a package and 18 napkins in a package. what is the least number of packages of cups and napkins that can be bought if each party guest get one cup and one napkin?

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
