In this question, we're trying to find how much Paul will pay per month in premiums.
We know that the plan costs $7,710 for a year
In order to find his premium cost per month, we need to get the total price for the year and divide it by 12, since there are 12 months in a year.
Solve:
7,710 ÷ 12 = 642.50
This means that he'll pay $642.50 a month.
Answer:
$642.50
