Bank pays 4% annual interest for the deposit. College will cost 35000 dollars per year and it will increase every year 5%. School lasts 4 years. First tuition payment is due on his 19th birthday. All the money parents saved will be transferred to son's account, where it will earn 2% annual deposit interest. From the same account tuition payments will be paid in the beginning of the year.
