Problem C. Your daughter will start college in five years. She has just informed you that she will take BS in Accountancy which will cost you Php 170,000 per year for four years ( cost assumed to come at the end of the year). Anticipating your daughter's ambition, you started investing Php 20,000 per year five years ago and will continue to do so for five more years. How much more will you have to invest each year for the next five years to have the necessary funds for your daughter's education? Use 10 percent as the appropriate interest rate throughout this problem. ( 10 pts)
