How do I complet this prblem (a, b and c as they relate to each other)? PLEASE SHOW ALL STEPS, MATH AND USE THE FORMULAS BELOW - NO EXCEL WORK PLEASE

formulas:

Present Vaule (PV) = C (cash flow) / (1 + interest rate)^{N (number of years)}

Future Vlaue (FV) = C (cash flow) x (1 + interest rate)^{N (number of years)}

Here is patrial of my work as I am stuck but don't know if it's correct

PV(CF4)=CF4/(1+I)4=20000/(1+8%)4=20000/(1+0.08)4=$14,700.60 You are pursuing a Bachelor's in Finance at a business school, and you will need $20,000 per year for the next 4 years to cover your college expenses. That is, you plan to withdraw $20,000 at the end of each of the next 4 years, starting one year from today. To support your college education, your parents decide to make a deposit today into a bank account paying an 8% annual interest. This deposit should be sufficient to cover the four $20,000 withdrawals you will make over the next 4 years. a. Draw a timeline to visualize the problem. b. How much must the deposit be? c. How much will be in the bank account immediately after you make the second withdrawal
