Suppose that $1200 is invested at 612%, compounded quarterly. How much is in the account at the end of 5 years?

asambeis [7]

Answer:

$\$1,656.50$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=5\ years\\ P=\$1,200\\ r=6\frac{1}{2}\%=6.5\%=6.5/100=0.065\\n=4$

substitute in the formula above

$A=1,200(1+\frac{0.065}{4})^{4*5}$

$A=1,200(1.01625)^{20}$

$A=\$1,656.50$
