Final answer:
The interest on a $215,750 house loan with a 15-year term and an interest rate of 2.5% is $80,812.50.
Step-by-step explanation:
The interest on a $215,750 house loan with a 15-year term and an interest rate of 2.5% can be calculated using the formula: Interest = Principal x Rate x Time. In this case, the principal is $215,750, the rate is 2.5% (or 0.025), and the time is 15 years. Plugging these values into the formula, we get: Interest = $215,750 x 0.025 x 15 = $80,812.50.
