interest = 750(3)(.0425) = 95.63

To calculate the interest earned, we will use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the final amount (including principal and interest)
P = the principal amount (initial deposit)
r = annual interest rate (in decimal form)
n = number of times interest is compounded per year
t = number of years

In this case, the principal amount (P) is $750, the annual interest rate (r) is 4.25% (or 0.0425 in decimal form), the interest is compounded annually (n = 1), and the time period (t) is 3 years.

Plugging these values into the formula, we can calculate the interest earned:

A = 750(1 + 0.0425/1)^(1*3)
A = 750(1 + 0.0425)^3
A = 750(1.0425)^3
A ≈ 750 * 1.1333
A ≈ $850

To find the interest earned, we subtract the original principal amount from the final amount:

Interest earned = A - P = $850 - $750 = $100

Therefore, you would earn $100 in interest after three years on an initial deposit of $750 with a simple interest rate of 4.25% compounded annually.

To calculate the amount of interest earned on a deposit with simple interest, you can use the formula:

Interest = Principal (initial deposit) * Rate * Time

In this case, the Principal (P) is $750, the Rate (R) is 4.25% (or 0.0425), and Time (T) is 3 years.

Using the formula, we can calculate the interest earned:

Interest = $750 * 0.0425 * 3
Interest = $95.63

Therefore, you would earn $95.63 in interest after three years on an initial deposit of $750 with a simple interest rate of 4.25% compounded annually.
