Step 1
Using this model, we can approximate the thereshold for a single person between the years 1999 and 2013.
y is the approximated thereshold in dollars.
Here, x=0 corresponds 1999
x=1 corresponds 2000.
x=2 corresponds 2001.
x=3 corresponds 2002.
x=4 corresponds 2003.
x=5 corresponds 2004.
So, x=13 corresponds 2012.
So, substituting x=6 in the given model, we get the approximated thereshold (in dollars) in 2005.
So, estimated thereshold in 2005=2.719(13)2+196.1(13)+8718
=2.719(169)+196.1(13)+8718
=459.511+2549.3+8718
=11827 dollars
Therefore, the approximated thereshold (in dollars) in 2012 is 11727 dollars.
