Two cars carry packages of the same value through the tax office. The escort did not bring enough tax money, so he used part of the goods as tax money. The first vehicle carried 120 packages, handed over 10 packages plus 240 yuan as tax; the second vehicle carried 40 packages, handed over 5 packages to the tax office, and received a refund of 80 yuan, which was just paid off tax. How much is the sales price of each package?
两辆汽车运送每包价值相同的货物通过收税处．押送人没有带足够的税款，就用部分货物充当税款．第一辆车载货120包，交出了10包货物另加240元作为税金；第二辆车载货40包，交给收税处5包货，收到退还款80元，这样也正好付清税金．问每包货物销售价是多少元？
