Answer:
8.0%
Explanation:
We have been given that James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be $76.57.
First of all, we will find the amount paid for the year using the monthly rate by multiplying $76.57 by 12 (1 year = 12 months).

Now, we will use percent change formula.






Therefore, Mr. Harmon is paying 8.0% more for the year using the monthly rate.
