Here is how to work on these, I'm sure someone else give us the right answer, but obviously it is the job I'd rather try to help you learn how to solve it. I conclude by making the 90% anyway ...
ReplyDeleteHave question wording is a little strange, would be in this "one months after leaving an additional 7% interest on the account, compounded (new to 1,181,000 $), but the interpretation of results and the number of really strange, and this emerging issues quite frequently, too, that I stay with 1181000 dollars as a "principal" and ignore the additional month (and monthly paying interest).
1) W is the amount withdrawn each month. T The total amount in the last few months, M withdrawn:
W = T x M
Since Frank is going to raise money from more than 300 months (25 years 62 to 87) that we know to withdraw M = 300. And the total amount withdrawn 1181000th T We resolve therefore:
1181000 x 300 W =
2) In the case of inflation, which is looking for two quantities of money, call Dollar (current D1) and D2 (future U.S. dollar). Call up the inflation rate and the number of years I, N. The formula is:
D2 = D1 x ((1 + i) ^ N))
(This is (more I) to the nth degree.)
In the case of Frank and retire, we know, D2 (the amount of finances in the future) - W is the equation in # 1 We also know that (one plus I) = 1.035.
The value of N is the difference between the present time is a Frankd old when they sign their first withdrawal or 20 years.
Log in W and the solution of the D1
W = D1 x (1.035 ^ 20)
Note - You can D1 (now expect the value of abstinence frank first time in 20 years) is less than W () the actual withdrawal, because the future of dollars less than the U.S. dollar is worth today account inflation.
I hope that helps.
