Answer: the amount of interest that he would pay is $490
Explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan or amount borrowed.
P represents the principal or amount taken as loan or borrowed.
R represents interest rate on the loan.
T represents the duration of the loan in years.
From the information given,
P = $3500
R = 3.5%
T = 4 years
Therefore,
I = (3500 × 3.5 × 4)/100
I = $490
