where D8 is equal to 4

Question 1 Benjamin, a software engineer, would like to invest in an attractive fund sold by a bank. The fund is to buy the stock of Big Bang Company. It is assumed that the fund can pay dividend steadily for the coming 10 years, which will generate an equivalent return of 5% annually, and the bank charge is negligible. He is thinking of investing ($10,000 + 100 x D8) at the end of each month in this fund for the purpose of using it for the down payment of purchasing a real property in the future. (a) How much down payment would he have accumulated at the end of 10th year? (Use 4 decimal places of the interest rate factor to do your calculation and round off your final answer to integer.)
