**Reiny**, Friday, April 26, 2013 at 9:05pmLet C(x) be the circulation function

given: C ' (x) = 4+5t^(2/3)

then

C(x) = 4t + 3t^(5/3) + c, where c is a constant

when x = 0 (now) , C(0) = 3000

3000 = 0 + 0 +c

so C(x) = 4t + 3t^(5/3) + 3000

so in 2 years, x = 2

C(2) = 8 + 3(2)^(5/3) + 3000

= appr 3018
