The way Jack dealt with his anger was to eat pie. Suppose he started with a whole pumpkin pie. On the first day, he ate one-fourth of the pie. Every day after that, he ate one-fourth of what was left. Write an equation modeling the amount of pie left over. (Let that be P) after t day. For the starting amount of pie, think of a whole pumpkin pie as 1. I am assuming that this would be written in an linear equation but I am not sure.
