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

• $25 - G

• $25 * G

• $25 / G

What does the variable G represent in the gift card example?

• The number of gift cards purchased

• The holiday season

• The total amount spent

• The cost of one gift card

How much does the local Community College charge per credit hour?

• $68

• $124

• $25

• $36

What additional fee is charged per student per semester at the college?

• $36

• $68

• $124

• $25

How would you write the expression for the total cost of college courses for C credit hours?

• $68 / C + $124

• $68 * C - $124

• $68 * C + $124

• $68 + C + $124

In the college courses example, what does the variable C represent?

• The total cost

• The additional course fees

• The number of credit hours

• The cost per credit hour

What is the cost of each table in the classroom pricing example?

• $12

• $36

• $68

• $25

How much does each chair cost in the classroom example?

• $36

• $25

• $12

• $68

What does the variable T represent in the tables and chairs example?

• The number of chairs

• The cost of one table

• The total cost

• The number of tables

How would you express the total cost for T tables and C chairs?

• $36 / T + $12 / C

• $36 * T - $12 * C

• $36 * T + $12 * C

• $36 + T + $12 + C
