The correct answer is: <span>a $100,000 life insurance policy at $0.55 per $1000 per month (more economical)
</span>
Explanation:
(1)<span>a $100,000 life insurance policy at $0.55 per $1000 per month
It means:
$0.55*100*12 = $660 [There are 100 thousands in $100000 and there are 12 months in the year]
(2)</span><span>a $100,000 life insurance policy at $170 per quarter.
It means:
$170*4 = $680 [There are 4 quarters in a year]
As $680 > $660 therefore Option (A) is the economical option.</span>
First, combine like terms.
3y+3x>-6x+12
Next, because there can not be the same variable on both sides, add 6x to both sides.
3y+9x>12
