Tim has just had his 45th birthday. He has two children. One will go to college 4 years from now and require four year beginning of year payments for college expenses, $18,000, $19,500, $20,500, and $21,500. The other will go to college 9 years from now and require four year beginning of year payments for college expenses, $23,000, $23,500, $24,000, and $24,500. In addition, Tim plans to retire in 20 years. Tim wants to be able to withdraw $100,000 per year (at the end of each year) from an account for 25 years. The first withdraw occurs on his 61st birthday. What equal, annual, end ofYyear amount must Tim save for each of the next 20 years to meet these goals if all savings earn a 8% annual rate of return?
