Answer:
The interest after 10 years on the principal amount is $340.
Step-by-step explanation:
Principal amount = $850
Rate of interest = 4%
Time Period = 10 years
Now, Simple Interest = [tex]\frac{P \times R \times T} {100}[/tex]
or, S I = [tex]\frac{850 \times 4 \times 10} {100}[/tex] = $340
So, the interest after 10 years on the principal amount is $340.
