Understanding the Cost of Movie Gift Sets

The video tutorial explains how to calculate the total cost of purchasing five gift sets, each containing three action movies and four dramas. It introduces variables 'a' and 'D' to represent the cost of action and drama movies, respectively. The tutorial guides viewers through writing and simplifying expressions for the cost of one and five gift sets, ultimately arriving at the simplified expression 15a + 20D for the total cost.

What does the variable 'a' represent in the context of the gift set problem?

• The total cost of a gift set

• The cost of each action movie

• The number of action movies in a gift set
