Answer:
To find the interest rate needed for a principal of $4,000 to increase to $4,500 in 10 years, we can use the formula:
A = P(1 + r)^n
Where A is the final amount, P is the principal, r is the interest rate, and n is the number of years.
In this case, we know that:
A = $4,500
P = $4,000
n = 10
So we can set up the equation as:
$4,500 = $4,000(1 + r)^10
To solve for r, we can divide both sides by $4,000:
$4,500/$4,000 = (1 + r)^10
1.125 = (1 + r)^10
We can find the interest rate by taking the 10th root of 1.125, and then subtracting 1.
r = (1.125)^(1/10) - 1
r = 0.059
So the interest rate needed for a principal of $4,000 to increase to $4,500 in 10 years, compounded annually, is 5.9%
