James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be

Deffense [45]

Answer:

8.0%

Step-by-step 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).

$\text{Amount paid for the year using the monthly rate}=\$76.57\times 12$

$\text{Amount paid for the year using the monthly rate}=\$918.84$

Now, we will use percent change formula.

$\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100$

$\text{Percent change}=\frac{\$918.84-\$850.80}{\$850.80}\times 100$

$\text{Percent change}=\frac{\$68.04}{\$850.80}\times 100$

$\text{Percent change}=0.0799717912552891\times 100$

$\text{Percent change}=7.99717912552891\%$

$\text{Percent change}\approx 8.0\%$

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