Cost and Variable Representation Problems

The video tutorial covers the concept of writing variable expressions through practical examples. It begins with calculating the cost of purchasing $25 gift cards, introducing the variable 'G' to represent the number of cards. Next, it explains how to determine the cost of college courses by using the variable 'c' for credit hours, incorporating additional fees. Finally, it demonstrates pricing tables and chairs for a classroom, using variables 't' and 'c' for tables and chairs, respectively. The tutorial emphasizes understanding and applying variable expressions in real-world scenarios.

If each gift card costs $25, how would you express the total cost for G gift cards?

• $25 + G
