数学题,最多的句型就是比较,A is less than B.别的没有什么特殊的了.
本题里还有 this tool being bought after the depreciation,being bought 是被动式的现在分词做后置定语,修饰tool.

一个画图工具的新价格在跌价后降了0.5元。在跌价后（购买）19个这种工具的总价，比在跌价前（购买）18个这种工具的总价要少6元。问这种工具的原价若干？
假设原价是 X, 那么新价格就是 X-0,5
18*X - 19*(X-0.5) = 6 求解 X
=> 18X - 19X + 9.5 = 6
=> -X + 9.5 = 6
可得出 X = 3.5 元

折旧后，画具的最新价格降了5毛钱。折旧后画具的19个部分总价比折旧前18个的价格少6块。问折旧前的价格？
19Y+6=18X
19X-19Y=0.5
不知道对不对。我站你一个
看你挺不错唉，丢人了。
