A family of 12 went to the local Italian restaurant for dinner.  Every family member ordered a drink and meal, 3 ordered an appetizer, and 6 people ordered cake for dessert.  Which expression can help us calcuate the bill.  Let d = drinks, m=meal, a = appetizer, and c = cake.

•  12d+ 12m + 3a + 6c
• 12d+ 12m + 12a + 12c
• 3d+ 6m + 12a + 6c
• 6d+ 6m + 3a + 6c

Simplify this expression 3(4𝑑+4𝑚+𝑎+2𝑐) by distributing.

•  12d+ 12m + 3a + 6c
• 12d+ 12m + 12a + 12c
• 3d+ 6m + 12a + 6c
• 6d+ 6m + 3a + 6c
