The total annual amount / (in millions
of dollars) of personal income earned in
a town and its annual population P (in
millions) can be modeled by I= 861t + 72,957/0.0059t+1
and
P= 0.0388t + 3.054, where t represents
the year, with t = 1 corresponding to
2011. Find a model M for the annual per
capita income. Estimate the per capita
income in 2013. (Assume t> 0.)
