1. Your sister would like your help planning for her new daughters college education. She has estimated that the cost of 1 year of college (tuition, room, and board) is currently $60,000 a year. The cost of college is estimated to increase at an annual rate of 5%. She would like you to figure out how much she would need to deposit at the end of each month for the next 18 years to cover her daughters four years of tuition assuming her deposits will earn 12% each year (1 % a month) (Note your account will earn interest a 1% a month even if you are not making monthly payments after you stop paying in at the end of the 18^th year).
