2.) For each yeart the number of trees in Forest A is represented by the functionA(t)=82(1.025)^t In a neighboring forest, the number of trees in Forest B is represented by the functionB(t)=115(1.029)^t Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after15years? By how many?

Round your answerto the nearest tree.

3.) Use the compound interest formula,A(t)=P(1+r/n)^nt After a certain number of years, the value of an investment account is represented by the expression10,300(1+0.04/12)^132 What is the value of the account?

Round your answer to two decimal places.
