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, you need to get rid of the parenthesis, so you need to distribute:
12(–1.4m + 0.4) = m + 0.2
-16.8m + 4.8 = m +0.2
Then subtract both sides by m:
-16.8m - m + 4.8 = m +0.2 - m
-17.8m + 4.8 = 0.2
Subtract both sides by 4.8:
-17.8m + 4.8 - 4.8 = 0.2 - 4.8
-17.8m = -4.6
Now, divide both sides by -17.8:
-17.8m/-17.8 = -4.6/-17.8
m ≈ 0.258
Plant 1 in 5th week = 1.75 + 1/2 (5) = 1.75 + 2.5 = 4.25
Plant 2 in 5th week = 1.75 + 3/4 (5) = 1.75 + 3.75 = 5.50
So, Difference = 5.50 - 4.25 = 1.25
In short, Your Answer would be Option B
Hope this helps!
