Pencils have the same unit cost regardless of the number sold, x pencils cost a total of $0.5, and n pencils cost a total of y dollar.
Column A Column B
n 2xy
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
C
解析
铅笔的单价(unit cost)与其销售量无关,x支铅笔卖$0.5,n支铅笔卖y美元。
解:本题的正确答案为(C)。单价不变,即0.5/x=y/n ,所以n=2xy
