Question

Quizplus · Accepted Answer

Using the formula for compound interest:
A = P(1+r/n)^(n*t)
where A is the total amount, P is the principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Plugging in the given values:
A = 4000(1+0.12/1)^(1*30)
A = 4000(1.12)^30
A = $1079800.05
The value is slightly less than $1081170, possibly due to rounding. Therefore, option A is true.
