Answer:

$3.10

Step-by-step explanation:

• For each visit ,(except 7),, he paid for both popcorn and the movie.

,

• He has a total of 39 receipts.

Therefore, the number of popcorns that he bought will be:


\begin{gathered} Number\; of\; popcorns=(39-7)/(2)=(32)/(2)=16\text{ popcorns} \\ \implies Number\; of\; movies=39-16=23\text{ movies} \end{gathered}

Since the movie tickets were $12.00 each, the amount spent on movies will be:


Movie\; Expense=23*\$12=\$276

We then use this to determine the amount spent on popcorns.


\begin{gathered} \text{Amount spent on popcorn}=Total-\text{Amount spent on movies} \\ =325.60-276 \\ =\$49.60 \end{gathered}

Recall that we earlier stated that Mario bought 16 bags of popcorn.

Therefore, the cost of a bag of popcorn will be:


(49.60)/(16)=\$3.10

Each bag of popcorn costs $3.10.Each bag of popcorn costs
