Best ResponseYou've already chosen the best response.0http://en.wikipedia.org/wiki/Compound_interest It is revinvested. That means you have to calculate \[5000\cdot 1.11^{4\cdot 5}\]

Best ResponseYou've already chosen the best response.011% = 0.11 but the original sum remains there too, so you have 1 + 11% = 1.11

Best ResponseYou've already chosen the best response.0i meant to write 1 + 0.11

Best ResponseYou've already chosen the best response.0ok, the full formula for compound interest is this \[A=P(1+rate)^{number of years * timez per year}\] so the timezperyear is 4 in your case as there are 4 quoters in a year

Best ResponseYou've already chosen the best response.0Ok, so that /4 was a mistake of yours. Well, what kind of functions does your calculator have? Is there a button that says "a^b" or maybe "x^y" ? Or otherwise there maybe buttons for "exp" and "ln"

Best ResponseYou've already chosen the best response.0in a calculator it would look like A=P(1+rate)^(numberofyears∗timezperyear)

Best ResponseYou've already chosen the best response.0like this: A = 5000(1+(11/100))^5∗4

Best ResponseYou've already chosen the best response.0which is: = 5000(1.11)^20

Best ResponseYou've already chosen the best response.0which is A = 5000 * 8.062311536 = 40311.55768 so now to get the compound interest subtract the 5000 from the answer, CI=40311.557685000 =35311.56

Best ResponseYou've already chosen the best response.0one more?? Using the rule of 72, how long will it take to double your money if you invest in an account earning 3% interest? Give units of time (days, weeks, months, or years)

Best ResponseYou've already chosen the best response.0wat does it mean tho by give units of time (days,weeks, months, years???

BecomeMyFan=D

Best ResponseYou've already chosen the best response.0or, if the question asks you how long it takes for the money to halve, divide 72 by percentage :)

Best ResponseYou've already chosen the best response.0it is there because the answer is not always in years, for example, if a question asks you how long it takes to double your money if you invest in an account earning 80% interest. It is IMPOSSIBLE in real life, but some questons might ask that, so, 72/80=0.9, which is 0.9 year, which is 365/10*9=328.5=329days

Best ResponseYou've already chosen the best response.0get it? but most of the times the answer is in years, so dont worry

Best ResponseYou've already chosen the best response.0can you see if these are right for me please. 6. Find the simple interest on $500 for 3 years at 7%. is it like this 500 x 0.07 x 3 = $105 7. Find the simple interest on $800 at 8.75% for 100 days. is it like this $800 x .0875 x 100/365 = $19.18
