For the following exercises, consider this scenario: For each year $t$, the population of a forest of trees is represented by the function $A(t)=115(1.025)^{t}$.In a neighboring forest, the population of the same type of tree is represented by the function $B(t)=82(1.029)^{t}$. (Round answers to the nearest whole number.) Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 20 years? By how many?
