Suppose your annual income is

1: I(t) = 63,000 + 2,000t (0 t 3)

dollars per year, where t represents the number of years since you began your job, while your annual expenses are

E(t) = 52,000 + 1,500t (0 t 3)

dollars per year. Find the area (in dollars) between the graphs of I(t) and E(t) for 0 t 3.
