How much interest was earned on $108,310 for 120 months if it was invested at a 4.5% simple interest
zvonat [6]

Answer:

$48,739.50

Step-by-step explanation:

You are going to want to use the simple interest formula for this.

I = Prt

<em>P = principal amount </em>

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

<em>t = time  (years)</em>

<em />

First convert 4.5% into its decimal form:

4.5% -> \frac{4.5}{100} -> 0.045

Next, we need to change 120 months into years:

\frac{120}{12} =10

<em>(10 years)</em>

<em />

Now, plug in the values into the equation:

I=108,310(0.045)(10)

I=48,739.50

The interest earned after 120 months was $48,739.50
