plans to pay the allowance to her daughter as described before but also wants the trust fund to decrease to 0 when she becomes an adult at 18 years of age. If the interest rate is constant at 1% per year, find the amount x(0) that she should put in the trust fund when her daughter is born.

The allowance is to start at $0 at the birth of her granddaughter, and then increase by $ 10 each month afterwards. I need a check on my answer which is 16000
