网考网试题解析：
To solve this problem, recognize that the percentages are the percent of interest the investment will make each year. Assign x as the amount of the inheritance invested at 5% and assign the amount of inheritance invested at 6% as (15,000-x). Because the total interest earned is the sum of the interest from the two investments, it can be expressed as 0.05x+0.06(15,000-x)=800. Solve for x: 0.05x+0.06(15,000)-0.06x=800 -0.01x+900=800 -0.01x=-100 x=10,000 Thus the quantity in Column A ($10,000) is greater than the quantity in Column B ($15,000-$10,000). document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
