Christian and some friends are going to the movies. At the theater, they sell a bag of popcorn for $3.50 and a drink for $3. How much would it cost if they bought 7 bags of popcorn and 3 drinks? How much would it cost if they bought p bags of popcorn and d drinks?

1) 33.5

2)3.50*p + 3*d

Step-by-step explanation:

1) 7*$3.50 = $24.5 is the price for 7 bags of popcorn

  3*$3 = $9 is the price for 3 drinks

  $24.5 + $9 = $33.5 is the total price for 7 bags of popcorn and 3 drinks

2) The price of p bags of popcorn = $3.50p

   The price of d drinks = $3d

   So the total price of p bags of popcorn and d drinks = 3.50*p + 3*d
