Rocio predicts that the amount of corn, C. in bushels, produced on her farm t years from now can be modeled by the function C(t)=80t+1000, while the price, P, in dollars, per bushel of corn t years from now can be modeled by the function P(t)=0.03t+5.

Let I be Rocio's predicted total income from producing cornt years from now.

Write a formula for I(t) in terms of C(t) and P(t)
