Final answer:
To calculate the amount of interest Beth will pay on her loan, multiply the principal, rate, and time. In this case, she will pay $42,840 in interest over 12 years.
Step-by-step explanation:
To calculate the amount of interest Beth will pay on her loan, we can use the formula:
Interest = Principal × Rate × Time
Where Principal is $35,000, Rate is 10.2% (0.102 as a decimal), and Time is 12 years.
Plugging in the values, we get:
Interest = 35,000 × 0.102 × 12 = $42,840
Therefore, Beth will pay $42,840 in interest over the 12-year loan period.
