Answer:
B.

Explanation:
Let t represent the number of tickets and p represent the number of buckets of popcorn.
We have been given that admission tickets cost $12 a piece, so the cost of t tickets will be 12t.
We are also told that a bucket of popcorn costs $7, so the cost of p buckets of popcorn will be 7p.
Since Art and his friends spent $62 at the movies. This means that cost of 7 buckets of popcorn and t tickets will be equal to $62.
We can represent this information in an equation as:

Since we know that standard form of equation is :
, therefore, option B is the correct choice.
