A pound week...why,she could almost pay that out of her housekeeping money......

是a pound a week,文章背景是她在一个商店看到了一个armchair,原话是,There was a card on the chair which said:"This fine chair is yours for less than a pound a week,"and very small at the bottom,"Cash price eighty-nine pounds fifty." A pound a week...why,she could almost pay that out of her housekeeping money and never miss it!

why 有感叹词的意思,根据这句话后面的感叹号,应该是对这个价格表示惊奇的意思,所以选择why

不过我对she could almost pay that out of her housekeeping money and never miss it这句话也不是很理解,是说她完全有能力支付还是什么呢?谁帮忙具体翻译一下~

应该是对前面的A pound week做的一个解释吧
A pound week，一个糟糕的星期，为什么这么说呢，（因为）她快连房租都付不起了。
