**Damon**, Friday, March 8, 2013 at 10:27pmFirst you are Mike, then John, now Paulie. Trying to confuse me?

d income/dt = 8.45 t^2 + 45.94 t + 723

so total income made per capita from year end 1994 to end of 1998 (begin 1999) is

integral of that from 1 to 5

= 2.817 t^3 + 22.97 t^2 + 723 t

at t = 5

then subtract at t = 1
