Answer:To calculate the total interest paid on a mortgage, you can use the following formula:
Total Interest = (Interest Rate/12) * (Total Number of Payments) * (Loan Amount)
In this case, the loan amount is the total cost of the mortgage, which is not specified in the question. However, we know that the payments are made for 15 years or 15*12 = 180 months.
We can use the formula above to find the total interest:
Total Interest = (0.04/12) * (2000 * 180) = 53,333.33 dollars
So, you paid $53,333.33 in interest over the life of the mortgage.
