A symbol that appears more than once in a question has the same meaning throughout the question.
A company plans to manufacture two types of hammers, type R and type S. The cost of manufacturing each hammer of type S is $0.05 less than twice the cost of manufacturing each hammer of type R.

选项

答案A

解析 Note that Quantity A and Quantity B both include the cost of manufacturing 1,000 hammers of type S. If you remove that cost from both quantities, the problem is reduced to comparing the cost of manufacturing 1,000 hammers of type R with the cost of manufacturing 500 hammers of type S. Since the cost of manufacturing each hammer of type S is $0.05 less than twice the cost of manufacturing each hammer of type R, it follows that the cost of manufacturing 1,000 hammers of type R is greater than the cost of manufacturing 500 hammers of type S. Thus the correct answer is Choice A.
This explanation uses the following strategies.
Strategy 8: Search for a Mathematical Relationship
Strategy 9: Estimate
