[計量] OG的第252頁
因為有一點小困惑(但好像是很簡單的題目..)
OG的 p.252 第200題
A store currently charges the same price for each towel that it sells.
If the current price of each towel were to be increased by $1, 10 fewer of
the towels could be bought for $120, excluding sales tax. What is the
current price of each towel?
答案是 $3.
但中間有一段 " 10 fewer of the towels " 這是什麼意思??
******************************
另外下面的201題
選項的 even number 是"偶數" 還是表"偶數個"?
我所謂的偶數個(不曉得是不是這樣叫@@)
像 1.2.3.4.5.6 總共就有六個數字 所以是偶數個
麻煩大家了 謝謝:~)
