Answer :
The calculation below shows that the total average credit card debt was or will be 12,330 in the year 2011.
How can we calculate the total average?
From the question, we have the following:
t = 2011 - 1995
t = 16
Therefore, the total average credit card debt in 2011 can be calculated as follows:
Total average credit card debt = 405t + 5850 ..................... (1)
Substituting t = 16 into equation (1), we have:
Total average credit card debt = (405 * 16) + 5850
Total average credit card debt = 6480 + 5850
Total average credit card debt = 12,330
