Answer:
Alright let's do this.
First Rewrite the question:
What operation do u use to find the cost of a drink and a popcorn for one person?
Ok when solving you need to take Maria's name and only use first letter.
I am just going to show the you how to do the question.
________________________________________________________
P= Popcorn (Cost: $8.00)
D= Drink (Cost: $5.00)
M (Maria) = $8 + $5 = (Answer)
F (Her Friend) = $8 + $5 = (Answer)
A quick way to solve to find the total cost for 2 people.
8 x 2 = 16
5 x 2 = 10
The total cost that Maria has to pay for her and her friend is $26.00.
The operation used is Addition or Multiplication.
