Question 363930: Directions:
Use the compound interest formulas A=P(1+r/n )^nt and A=pe^rt to solve.
Suppose that you have $7000 to invest. Which investment yields the greater return over 9 years: 8.75% compounded continuously or 8.9% compounded semiannually?
Can someone help me? I have to show all my work, so any help is greatly appreciated.

For the 8.9% compounded semi-annually:
, 
, 
, and 
, and the formula to use is:
^{nt})
For the 8.75% compounded continuously,
, , , 
is the base of the natural logarithms and the formula to use is:
All you have to do is put the numbers in their places and do the arithmetic.

My calculator said it, I believe it, that settles it
