To save money over the next three years, Zhu Ming plans to buy a new, more energy-efficient washing machine. Last year Zhu Ming washed 200 full loads of laundry. If Zhu Ming uses the new machine to wash 200 loads of laundry per year for the next three years, the savings on utility bills will more than offset the purchase price of the new machine. The expected cost of maintaining the new machine is no greater than that of the current machine. Moreover, the cost of installing the new machine is not significant.
Which of the following would be most useful to know in deciding whether buying a new washing machine is likely to help Zhu Ming save money over the next three years?
A. Whether the warranty on the new washing machine can be extended beyond the usual term of three years.
B. Whether the load capacity of the new washing machine is smaller than that of Zhu Ming’s current machine.
C. Whether Zhu Ming plans to purchase other energy-efficient durable goods during the next three years.
D. Whether the new washing machine uses laundry detergent that reduces wastewater pollution.
E. Whether the new washing machine is of the same brand as Zhu Ming’s current machine.

The argument suggests that Zhu Ming will save money by purchasing a more energy-efficient washing machine, assuming he washes 200 loads per year for the next three years. The key point is whether the savings on utility bills will offset the purchase price, and the maintenance costs and installation costs are deemed insignificant.
Pre-thinking: To determine if buying the new washing machine will actually help Zhu Ming save money, we need to consider factors that could impact his ability to save on utility bills. One such factor could be whether the load capacity of the new machine is smaller than the current one. If the new machine has a smaller load capacity, Zhu Ming might need to run more loads than anticipated, which could increase energy and water usage, thus reducing or eliminating the savings.
A) Whether the warranty on the new washing machine can be extended beyond the usual term of three years.
The warranty length doesn't affect whether Zhu Ming will save on utility bills over the next three years.
B) Whether the load capacity of the new washing machine is smaller than that of Zhu Ming’s current machine.
This is the most relevant factor. If the new machine has a smaller load capacity, Zhu Ming might have to run more loads, increasing his utility costs and reducing the expected savings. Aligns well with our pre-thinking.
C) Whether Zhu Ming plans to purchase other energy-efficient durable goods during the next three years.
Other purchases don't directly affect the savings from the washing machine.
D) Whether the new washing machine uses laundry detergent that reduces wastewater pollution.
This is environmentally relevant but does not impact the financial savings on utility bills.
E) Whether the new washing machine is of the same brand as Zhu Ming’s current machine.
The brand of the machine is irrelevant to the savings on utility bills.
The correct answer is B) Whether the load capacity of the new washing machine is smaller than that of Zhu Ming’s current machine. This would directly impact the number of loads required, thus affecting the expected savings on utility bills.
