Use Geometric Sequence formula:
S = F x [1 - R^N ] / [1 - R], where S=Sum, F= First term, R=Common ratio, N=Number of terms
S = 100 [1 - 1.02^8] / [1 - 1.02]
S = 100 [1 - 1.1716593810022656] / [- 0.02]
S = 100 [ - 0.1716593810022656 ] / [-0.02]
S = 100 x 8.58296905011328
S = $858.30 - what Evelyn will make in 8 weeks.
