■2道英语数学小题,麻烦帮我解决下
1.A disconut of 25% was allowed on the price of a book.Determine the reduced price if the discount was EUR 6.48.
2.The adcertising costs used to represesent 6% of the total costs.In the total costs,the other costs increase by 5%.How many percent should the advertising costs be decreased,if the increase in the total costs is allowed to be only 2%and the reduction in the total costs is made in the advertising costs only?
请帮我翻译下,并且作出回答,谢谢:)
1 每本书的价格允许25%的折扣,请问如果折扣是 EUR 6.48,那么折扣价格是多少?
此时6.48对应25%,那么原价格是:25.92,折扣价格是:19.44.
2 广告费用占到总费用的6%,其他费用上升了5%.如果总费用只允许增加2%,而总费用削减的数额只能从广告费用里减去,那么广告费用要削减多少个百分比?
答案是45%
