Assume that you work from age 25 to age 65. At the end of each year, you contribute C to your pension fund, which is invested at a yearly rate r = 5%. At age 65 you retire and plan to consume $20,000 each year, until you die. Assuming that you die at age 85, and that interest rates remain constant, how much should you save each year? How does the result change if, due to your reckless lifestyle, you assume that departure will occur at age 75?
Sally purchases a perpetuity immediate with annual payments that pays $1000 today
and Payments increase by 2% per year. She will pay for it with a single payment exactly 3 years
from today. Assume a constant force of interest of 10%. Calculate the size of the payment at
time 3.
An investor deposits an initial amount of money (Yo) into a bank
account that offers a simple (annually compounding) interest rate
(r). The bank charges a fixed annual fee (b). The bank charge is
debited after the interest is accumulated. Write down a difference
equation that describes how the account balance (Yt) changes
over time (t), then solve the equation analytically.
If the interest rate is r = 0.1(10%), the bank charge is b = 100 and the
investor projects that the account balance in year t = 3 is $2,464, then the

- Suppose an investment account is opened with aninitial deposit of 10,500 earning 6.25 interest,compounded continuously. How much will theaccount be warm after 25 years?arrow_forwardPresent value is the amount of money that must be invested now at a given rate of interest to produce a given future value. For a 1-year investment, the present value can be calculated using Present value = Future value 1 + r , where r is the yearly interest rate expressed as a decimal. (Thus, if the yearly interest rate is 8%, then 1 + r = 1.08.) If an investment yielding a yearly interest rate of 13% is available, what is the present value of an investment that will be worth $4000 at the end of 1 year? That is, how much must be invested today at 13% in order for the investment to have a value of $4000 at the end of a year? (Round your answer to two decimal places.)arrow_forwardIn 1992, the four-year cost of tuition at UMass was $19,000. Tuition is expected to rise 79% over the following decade.

(b) How much should parents of a child born in 1992 invest at the time of the child's birth at 8% annual interest compounded continuously in order to have sufficient tuition for their child at age 18? (c) A family is able to invest $5,000 in 1992 at 9% annual interest, compounded monthly. How long will it take for this amount to grow sufficiently to cover 4 years' tuition?
