某中学组织七年级学生秋游，由王老师和甲、乙两同学到客车租赁公司洽谈租车事宜。

(1) 两同学向公司经理了解租车的价格。公司经理对他们说：“公司有45座和60座两种型号的客车可供租用，60座的客车每辆每天的租金比45座的贵100元。”王老师说：“我们学校八年级昨天在这个公司租了2辆60座和5辆45座的客车，一天的租金为1600元，你们能知道45座和60座的客车每辆每天的租金各是多少元吗？”甲、乙两同学想了一下，都说知道了价格。

你知道45座和60座的客车每辆每天的租金各是多少元？

(2) 公司经理问：“你们准备怎样租车？”，甲同学说：“我的方案是只租用45座的客车，可是会有一辆客车空出30个座位”；乙同学说“我的方案只租用60座客车，正好坐满且比甲同学的方案少用两辆客车”，王老师在一旁听了他们的谈话说：“从经济角度考虑，还有别的方案吗？”如果是你，你该如何设计租车方案，并说明理由。

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.

   On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor decided that single men could become better soldiers than those with wives, he didn’t allow marriage.

   But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.

   Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends.
