Question 20719: Five years ago, $10000 was invested at 6%/a compounded semi-annually. Today the investment rates have risen to 7%/a compounded annually. If the original investment and accumulated interest is rolled into the new investment conditions, how much will it be worth in five years.
Use A=P(1+i)^n
I know for 6% P=10000, i = 0.03 but I don't know what n =?
I know for 7% P=10000, i = 0.07 But I don't know what n =?

A=AMOUNT=PRINCIPAL+INTEREST..P=PRINCIPAL
YOU USED I FOR RATE PER TERM PER DOLLAR.. WE USE R FOR
RATE AND I FOR INTEREST..N=NUMBER OF TERMS...
> I know for 6% P=10000,CORRECT i = 0.03 VERY GOOD..IT
IS RATE PER TERM HERE TERM IS SEMIANNUAL SO INTERET
RATE IS HALF OF 6% THAT IS 3% THAT IS = 0.03 PER
DOLLAR..but I don't know
> what n =? AS I SAID N = NUMBER OF TERMS FOR 5 YEARS
=10 HALF YEARS....SO N=10
> I know for 7% P=10000,NO...IT IS ACUMULATED INTEREST
AND PRINCIPAL..SO YOU SHOULD USE A OBTAINED FROM ABOVE
CALCULATION AS P HERE. i = 0.07 VERY GOOD..But I don't
know
> what n =?..N=5 IN THIS CASE AS NUMBER OF TERMS IN 5
YEARS IS 5.
> NOW FIND A USING THE ABOVE VALUES.
