22. Find the balance in an account with $900 earning 6.5% compounded<br> quarterly after 4 years
Helen [10]

Answer:

$1,164.80

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

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

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, we need to change 6.5% into a decimal:

6.5% -> \frac{6.5}{100} -> 0.065

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

A=900(1+\frac{0.065}{4})^{4(4)}

A=1,164.80

The balance after 4 years will be $1,164.80
