Answer: c. She can save $25.78 by paying the premium annually.
We arrive at the answer as follows:
Loraine's annual insurance premium $1,287.50
If she wants to pay monthly, she'll have to pay 8.5% of her annual premium.
So, her monthly premium will be
![\mathbf{1,287.50* 0.085 = 109.4375 \approx 109.44}](https://img.qammunity.org/2019/formulas/business/college/dem2tkm7k56g2bkhnv7bbuvj9uanx7s9z2.png)
Her total annual payment for insurance will be
![12*109.44 = 1313.28](https://img.qammunity.org/2019/formulas/business/college/6o52v7t6ak4ytcdnnixlvdroyi8v80j92n.png)
Her savings by paying insurance annually is
![\mathbf{1313.28 - 1287.50 = 25.78}](https://img.qammunity.org/2019/formulas/business/college/inwnc9pyqt6u8upt43l4wn0y5b0r24n1ce.png)
