If dp/dt = e^1/2t −100, then integrating gives p(t) = (1/2) * e^1/2t - 100t + C. Now, with the initial condition p(0) = 1000, you can find C. Done! Don't forget to vote best answer ! Hopefully no one will spoil you the answer. That...

dN/dt = -No*e^(-t). When No = 0.40*5,000,000 = 2,000,000, then at t = 1 you have -dN/dt = 2000000/e, which is much more than 270671. So I guess what is meant by "t years beyond 1990" is t years beyond the...
