Answer:
Simple interest is: $2976
Account balance is: $9176
Explanation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year,
then, solving our equation
I = 6200 × 0.12 × 4 = 2976
I = $ 2,976.00
The simple interest accumulated
on a principal of $ 6,200.00
at a rate of 12% per year
for 4 years is $ 2,976.00.
