Jamie wants to save money to meet two objectives. First, he would like to be able to retire 30 years from now with retirement income of $17,500 per month for 25 years, with the first payment received 30 years and one month from now. Second, he would like to purchase a cabin in River Grove in 10 years at an estimated cost of $345,000. He can afford to save $2,350 per month for the next 10 years.

If he can earn an APR of 10% pa (compounded monthly) how much will he have to save each month in years 11 through 30?
