 Mrs. Davis is making a poster of math formulas for her students. She takes the 8.5" x 11" paper she printed the formulas on to the photocopy machine and enlarges the image so that the length and width are both 150% of the original. She enlargea the image a total of 3 times before she is satisfied with the size of the poster. Write an explicit formula for the sequence that models the area of the poster, A, after n enlargements. What is the area of the final image compared to the area of the original, expressed as a percent increase and rounded to the nearest percent?
