Answer:
$14400
Explanation:
Using the formula for calculating the simple interest expressed as;
SI = Principal * Rate * Time/100
Given
Principal = $6000
Rate = 12%
Time = 20 years
Substitute into the formula;
SI = 6000 * 12 * 20/100
SI = 60*12*20
SI = 14,400
hence the interest worth after 20years will be $14400
