In the far away town of Catherby all the locals do day and night is fish. Always by the shore, always holding their rods. 在一個遙遠的Catherby鎮裡，所有的當地人日日夜夜做的就是釣魚。沿岸總是不斷的 有人拿著釣竿釣魚。 One day a young man named Edwin decides he doesn't want to simply wait for the fish to come to him, instead he wants to go to the fish and catch them on the open waters with a net. 有一天一個叫做艾德溫的年輕人決定不想要僅僅等魚上鉤，相反地他想要出海用魚網 來捕魚。 He visits the local manor to request a license to use a boat from his Lord, only to be told there is a charge of 4,400 ￠τ a month for the license, but he must purchase his own boat, and net separately after getting his license from the local Fishery. 他拜訪村裡的村長，請求許可讓他可以使用魚船，村長只是告訴他一個月的許可證是 4,400￠t，但是必須在取得許可證後才可在當地的魚市場裡購買他自己的魚船及漁網。 The Boat and Net together cost a total of 1,700 ￠τ. Oh how would be long for the chance to go out on the open sea, but alas he has only as of yet managed to save 800 ￠τ. 魚船和漁網一共要花費1,700￠t。噢，需要多久才能有出海捕魚的機會呢，他當時身 上僅有想方設法所存下的800￠。 In order to earn the remainder he needs to find himself a paying job .. And finds one working at the Fishery where he later needs to buy the equipment he needs. They offer him a discount of 5% on any equipment, plus basic wage of 250 ￠τ a week, and a bonus of 5 ￠τ for every fish he sells, which will be paid weekly. 為了獲得足夠的差額他需要一個有報酬的工作。最後他在漁業市場（一個在他以後可 以買他所需要的設備）裡找到一個工作。他們給他提供每週250￠t的薪水及購買任何 設備有5%的折扣，且每賣出一條魚有獎金5￠t。 Question: Assuming Edwin manages to sell 20 fish a week, how long will it take him to earn the rest of the funds he needs? 問題︰假定艾德溫設法每周賣出20條魚，他賺到所需要的其餘資金要花費多久？ 以上是我透過眼睛醫生的幫忙所翻譯出來的題目，不知道有沒有任何地方翻譯錯誤？ 依照這個物價來看的話，賣的魚至少不會是吳郭魚之類的小魚，應該是鯛魚或其他比較 大尾的吧，會不會是鮪魚呢XD --- 透過EXCEL的幫忙，算出來是在第15週結束前可以達成買到許可證及船和漁網所需要 的錢，還有請各位板友幫忙看看答案是否有問題？ --
