"Cory has 15 die-cast cars in his collection. Each year his collection increases by 20%."
That means Cory has an $\color{red}{initial~ amount}$ of $\color{red}{15}$ cars and the rate of growing\increasing is $\color{red}{0.2}$,,,so that the relation would be an exponential growing function as follows:
