A sibling will start his/her first year at Local University in the Fall of 2024. Annual tuition and books are $15,000 and are to be paid in semi-annual installments at the opening of each semester. Assuming that your parents have invested this money in an account that earns 5% p.a., how much must there be in the account to fund his/her four-year education as of September 1st, 2024?

Referring to the previous question and your answer in previous question, now assume that your parents inform your sibling that there is only $40,000 in the account as of September 1st, 2023. Apparently, they have spent more money on your education than they anticipated. How much must your parents deposit into the education account at the end of each month, over the next 12 months, to make up for the difference needed to fund your siblings education?
