Understanding Credit Card Debt Calculation

The video tutorial explains how to use the expression 402t + 5,480 to calculate the average credit card debt in U.S. households for years after 1995. It emphasizes that 't' represents the number of years after 1995, not the year itself. The tutorial demonstrates how to calculate the debt for the year 2019 by determining 't' as 24, then substituting it into the expression. The process involves simplifying the expression using multiplication and addition to arrive at the final debt amount of $15,128. The video concludes by reiterating the importance of understanding the expression and its components.
