Using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the
equation
10.0y 4.55x = 581
where x is the number of years after 2000.+

Disposable income, the amount left after taxes have been paid, is one measure of the health of the economy. Using U.S.
Energy Information Administration data for selected years from 2015 and projected to 2040, the U.S. real disposable income
per capita (in dollars) can be approximated by the equation
I 707.6t + 39,090
where t is the number of years after 2015.
(a) What t-value corresponds to 2021?
t =
A $653,000 property is depreciated for tax purposes by its owner with the straight-line depreciation method. The value of
