Create an exponential to describe $100 at 2% interest compounded annually for x years

zysi [14]

Answer:

$A=100(1.02)^{x}$

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

$t=x\ years\\ P=\$100\\ r=2\%=2/100=0.02\\n=1$

substitute in the formula above

$A=100(1+\frac{0.02}{1})^{1*x}$

$A=100(1.02)^{x}$

.70x= 17.50
Divide both sides by .7 and the answer is 25.
