Final answer:
The interest rate in the mortgage is 3%.
Step-by-step explanation:
To calculate the interest rate in a mortgage, we need to use the formula:
Interest payment = Loan amount × Interest rate
Given:
- Interest payment = $1,500
- Loan amount = $50,000
- Payments are made every 3 months
Let's solve for the interest rate:
Interest payment = Loan amount × Interest rate
$1,500 = $50,000 × Interest rate
Interest rate = $1,500 / $50,000
Interest rate = 0.03
Converting to a percentage: 0.03 × 100 = 3%
Therefore, the interest rate in the mortgage is 3% (option B).
