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。
不是19pieces of this tool吗?那不是工具的19个部分吗?怎么会等同于工具本身呢?...
