$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$1500\\ r=rate\to r\%\to \frac{r}{100}\dotfill &0.04\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &1,2,3,4,5 \end{cases}$

$\bf A=1500\left(1+\frac{0.04}{1}\right)^{1\cdot 1}\implies A=1500(1.04)^1\implies A\approx 1560\\\\\\A=1500\left(1+\frac{0.04}{1}\right)^{1\cdot 2}\implies A=1500(1.04)^2\implies A\approx 1622.4\\\\\\A=1500\left(1+\frac{0.04}{1}\right)^{1\cdot 3}\implies A=1500(1.04)^3\implies A\approx 1687.3\\\\\\A=1500\left(1+\frac{0.04}{1}\right)^{1\cdot 4}\implies A=1500(1.04)^4\implies A\approx 1754.79\\\\\\A=1500\left(1+\frac{0.04}{1}\right)^{1\cdot 5}\implies A=1500(1.04)^5\implies A\approx 1824.98$

many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $750 on a cre

mash [69]

The answer is E.

First you need to find the rate. You must divide 1.8 by 100

1.8/100 = .018

Then add 1.

.018 + 1 = 1.018

Then times the starting amount with 1.018. The starting amount 750

750(1.018) = 763.5.
As you can see, in option E that is the 2nd number.

Now we must find the next number.

You will do 750(1.018)^x

x represents the time.

763.5 was the first month.

750(1.018)^2 is the 2nd month.

750(1.018)^2 = 777.244 which is the 3rd number in option E
