An increase of 1.5 % = 1.015
Year 1, 2, 3,.........................., 30.
30000, 3000(1.015), 30000(1.015)²,........... 30000(1.015)²⁹
Her Total Income is sum over the thirty 30 year period:
Sn = a(r^n - 1) / (r - 1); a = 30000, r = 1.015, n = 30
Sn = 30000 ( 1.015^30 - 1) / (1.015 - 1)
= 30000 (1.56308022 - 1) / (0.015) = 1126160.44
Total = $ 1 126 160.44
