To solve this problem, first calculate the value of the quantity in each column. The quantity in Column A is (30% of 60)+ 70. Because 30% of 60 can be represented as 0.30(60), or 18, the quantity (30% of 60)+70=18+70, or 88. Similarly, (70% of 60)+30=0.7(60) + 30, or 42+30, which equals 72. Thus the quantity in Column A (88) is greater than the quantity in Column B (72). document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
