How to solve this Annuities question

Setup

Setup

Payment k is the first payment grown by 15% for k minus 1 years.

Pk=100(1.15)k1P_k=100(1.15)^{k-1}

Model

Discount the ten-term geometric stream at 5%.

PV=k=110100(1.15)k1(1.05)kPV=\sum_{k=1}^{10}\frac{100(1.15)^{k-1}}{(1.05)^k}

Evaluating the finite geometric sum gives 1483.621512.

PV=1483.62151192PV=1483.62151192

Answer

Answer

The annuity present value is approximately 1,484, so choice E is correct.

PV1484(E)\boxed{PV\approx1484\quad\text{(E)}}
