Answer:

Rate of interest = 45.68%

Step-by-step explanation:

In this question, we have to calculate the rate of interest.

to calculate the interest rate we use the formula [tex]R=\frac{I}{PT}[/tex]

Here it is given, the Principal amount = 2,700

Amount after 3 years - 6,400

So the Interest = 6,400 - 2,700 = $3,700

Now we put the values in the formula :

[tex]R=\frac{3,700}{(2,700)(3)}[/tex]

[tex]R=\frac{3,700}{8,100}[/tex]

R = 0.45679

Converting in to percentage = 0.45679 × 100 = 45.679%

Rate of interest = 45.68%
