How much will you have after 10 years? 4) You want to have $20,000 5 years from now. How much must you save each year if the interest rate is 6%? 5) You can save $4,000 each year. If you want to have $40,000 after 6 years, what interest rate would you need to earn? 6) You can save $4,000 each year.

How much will you have after 6 years? 8) You are getting a 30‐year mortgage at an interest rate of 6% per year. If you borrow $300,000, what will be your monthly payment? 9) You are getting a 30‐year mortgage at an interest rate of 6% per year. If you can pay $2,000 per month, what is the most you can borrow? 10) You can save $200 per month. If you earn 12% per year compounded monthly, how much will have after 8 years? 11) If you earn 12% per year compounded monthly and you want to have $40,000 after 8 years, how much must you save per month? 12) If you can save $200 per month and want $40,000 after 8 years, what (annual) interest rate compounded monthly do you need to earn? 13) If you can save $200 per month and want $40,000 and earn an annual interest rate of 12% compounded monthly, how long would it take in years? 14) You have a 4‐year auto loan at 18% per year compounded monthly. If you want to borrow $20,000, what would be your monthly payments? Assume that payments are made at the start of the month. 15) You are planning on working and saving for 30 years at which point you’ll live off your savings while you are retired. Assume that you earn 3% compounded monthly on your investments when you are retired and 6% compounded monthly when you are working. If you plan on being retired for 20 years and need $4,000 per month when retired, how much must you save each month when you are working?
