If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.

You invest 300$ at 4% intrest compounded every year what will your balance be after 5 years?

frutty [35]

Answer:

Option D $\$365.00$

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

$t=5\ years\\ P=\$300\\ r=0.04\\n=1$

substitute in the formula above

$A=300(1+\frac{0.04}{1})^{1*5}$

$A=300(1.04)^{5}$

$A=\$365.00$
