5. A father decides to establish a savings account for his child's college education on the day his
son is born. Any money put into the account will earn an interest rate of 10%. The father will
make a series of annual deposits in equal amounts from the child's 1st birthday through the
18th birthday so the child can make four annual withdrawals from the account in the amount of
Php 200,000 on each of his 18th, 19th, 20th, and 21st birthdays. Assuming that the first
withdrawal will be made on the child's 18th birthday, calculate the required 18 equal annual
deposits.
