Help me plan a picnic for 12 people.  Here is a list of items needed:
      hamburg buns (packages of 8) - $1.20
      packages of hamburger meat (4 burgers in a pack) - $2.80
      watermelon - $5.00
      cupcakes (sold by the dozen) - $3.00
      soda (sold in packs of  6 cans) - $2.00
If each person eats 2 hamburgers, 2 cupcakes, 1 soda, and shares the watermelon, how much will it cost for the food ?
