Final answer:
The total interest paid on a 30-year mortgage for $235,000 at a 7% interest rate, compounded monthly, is $331,230.69.
Step-by-step explanation:
To calculate the total interest paid on a 30-year mortgage with a principal amount of $235,000 and an interest rate of 7% compounded monthly, we can use the formula for compound interest:
Interest = Principal * (1 + (interest rate / number of periods))^(number of periods * number of years) - Principal
Plugging in the values, we get:
Interest = $235,000 * (1 + (0.07 / 12))^(12 * 30) - $235,000
Calculating this, we find that the total interest paid on the mortgage is $331,230.69.
