Answer:
Explanation:
Answer: 
I = $ 800.00 
 
Equation: 
I = Prt 
 
Calculation: 
First, converting R percent to r a decimal 
r = R/100 = 5%/100 = 0.05 per year, 
then, solving our equation 
 
I = 4000 × 0.05 × 4 = 800 
I = $ 800.00 
 
The simple interest accumulated 
on a principal of $ 4,000.00 
at a rate of 5% per year 
for 4 years is $ 800.00. 
hope it helps :)
