Answer:
Option b ($150,000 decrease) is the correct answer.
Explanation:
Given:
Fixed manufacturing overhead,
= $65
Units,
= 10,000
According to the question,
Current cost is:
= 
= 
($)
The expected cost will be:
= 
By substituting the values, we get
= 
= 
= 
then,
= 
= 
($)
Thus the above is the right answer.
This problem is actually under the subject of Mathematics, particularly, Algebra. For work problems, you can use a convenient technique of dimensional analysis. This is done by multiplying units of measurement, then cancelling out like terms in order to come up with the units of the final answer. For this problem, the total amount of liters is 2,100. So, the equation would be
Volume of Kelly's family + Volume of Stewart's family = 2,100
However, we are only given the rates for each family in liters per hour. To come up with the final answer with a unit of measurement in Liters, we must multiple the rate of L/hour with the individual time. Let x be the time Kelly's sprinkler was used, and y for Stewart's family.
(20 L/h)(x hours) + (40 L/h)(y hours) = 2,100
This is the first equation. The second equation is the total time.
x + y = 65 hours
Rearranging the equation, y = 65 - x. Let's substitute this to the first equation.
20x + 40(65-x) = 2,100
Solving for x, then substituting it to the second equation to obtain y,
x = 25 hours
25 + y = 65
y = 40 hours.
Thus, Kelly's sprinkler was used for 25 hours, while Stewart's sprinkler was used for 40 hours.
