For 1995 through 2005, the number n (in thousands) of units produced by a manufacturing company can be modeled by n = 1.4t + 2.1 and the profit p (in dollars per unit) can be modeled by p = 1.4t - 2.1 where t is the number of years since 1995.
a. write and simplify a polynomial that models the company total profits t (in thousands of dollars) in terms of the number of years since 1995.
b. what was the company's total profit in 2002?
