What is the interest rate if a principal of $700 earns $196.00 in interest in seven years?
solniwko [45]

Answer:

4%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

r=\frac{I}{Pt}

<em>P = initial balance</em>

<em>I = interest</em>

<em>t = time</em>

<em />

Plug the values into the equation:

r=\frac{196}{(700)(7)}

r=.04

The last step is to convert 0.04 into a percent:

0.04(100) = 4

The interest rate is 4%.
