A park started with 12 oak trees, and the number of oak trees increased at a rate of 25% each year. Write the function that models the situation, substituting numerical values for A and r into the expression.

Answer:The function which models the situation is as The number of oak trees increase after n year = 12 ×  [tex](1+\frac{25}{100})^{n}[/tex]Step-by-step explanation:Given as :The number of oak trees planted in park = 12The rate at which number of tree increase each year= 25%Now,The number of oak trees increase after n year = Present numbers of tree × [tex](1+\frac{Rate}{100})^{n}[/tex]Or, The number of oak trees increase after n year = 12 × [tex](1+\frac{25}{100})^{n}[/tex]Hence The function which models the situation is as The number of oak trees increase after n year = 12 × [tex](1+\frac{25}{100})^{n}[/tex]  Answer
