Polly's Party

solution

  • Cupcakes: 3 boxes of 6
  • Plates: 2 packs of 10
  • Ice-cream sandwiches:
    4 boxes of 4
  • Juice boxes: 3 packs of 5
TOTAL NUMBER OF BOXES OR PACKS = 12

 

explanation
  • Cupcakes:
    3 boxes of 6 = 18 cupcakes in all
  • Plates:
    2 packs of 10 = 20 plates in all
  • Ice-cream sandwiches:
    4 boxes of 4 = 16 sandwiches in all
  • Juice boxes:
    3 packs of 5 = 15 boxes in all

They had 12 items, so they could use the express check-out line. They had 15 juice boxes and more of everything else. Therefore, Polly could have 15 people at the party, including herself.
