Answer: 5.6%
Step-by-step explanation:
Formula for simple interest: Interest = [tex]\dfrac{P\times R \times T}{100}[/tex], where P= Principal , R = Rate of interest , T= Time.
Given: P= $3,875, T= 3 years , Interest = $651
Substitute all values in formula, we get
[tex]651=\dfrac{3875\times R\times3}{100}\\\\\Rightarrow\ R= \dfrac{65100}{3875\times3}\\\\\Rightarrow\ R=5.6\%[/tex]
Hence, the required rate = 5.6%
