I would appreciate some help with questions 1B and 2A, 2B!

Thanks in advance

ASSIGNMENT #1 (15 marks) Name (Last, First):_______________________________ Student No.:_________________ USE 4 DECIMAL PLACES (rounded) i.e., 1.2345% or .6789- for intermediate calculations and round your final answer to two decimal places. For amounts involving dollars and cents, use two decimal places. Question 1 (6 marks) (a) Assume that a pension plan offers to pay $300,000 on a person's retirement (his/her sixty-fifth birthday) or a semi-annual annuity for the remainder of the person's life - i.e., starting 6 months from the date of retirement and including his/her date of death. Interest rates are 8 percent compounded semi-annually, and a person's life expectancy has been determined statistically as being 80 years. Calculate the amount of the annuity that would make a person indifferent between the options? (3 marks) (b) A person joins a pension plan at age 35. How much will s/he have to pay into the pension fund each year in order to accumulate a balance of $250,000 by the time s/he retires (age 65)? Assume that the payments start on his/her 35th birthday and the final payment is on his/her 60th birthday. Interest rates are 7% compounded annually. (3 marks) 1 Question 2 (9 marks) (a) Laura Smith is planning for her and her husband Luke's retirement. Both Luke and Laura expect to retire in 35 years (when they turn 65). The life expectancy of men is 75 years and the life expectancy of women is 85 years (i.e., assume that they die the day before their 75th or 85th birthday). During retirement (while they are living), the couple wants to withdraw $10,000 at the beginning of each year from their savings account- $5,000 for each of them. Assume that the interest rate during their retirement is 10 percent compounded annually; the interest rate after Luke dies is 12% compounded semiannually; and, the interest rate prior to retirement is 9 percent compounded annually. How much will they have to deposit in their joint savings account each month (beginning one month from now and ending on their retirement date)? (6 marks) 2 (b) How would your answer change if Luke and Laura Smith expect to inherit $40,000, 5 years from now? Assume that, at that time, they will spend $10,000 for a two-week luxury all-inclusive cruise, spend $25,000 to buy top-of-the-line stainless steel appliances for their kitchen, and save the rest for their retirement. Assume equal monthly payments throughout the 35 years to retirement- i.e., the same monthly payments beginning one month from now and ending on their retirement date. (3 marks) 3
