: 4.Sx/T(T-S)
: 5.x(T-S)/T
: 正確答案是4 為什麼不是3 題目問的應該是"剩下的人要多付多少"沒錯吧
: 還是我誤會題目的意思了

: At the end of each year, a certain credit card company pays a bonus to each
: of its credit card holders based on the amount, up to $10,000, that the
: cardholder charged throughout the year. A 0.5 percent bonus is paid on the
: first $1,000 charged, a 1.0 percent bonus is paid on the next $2,000 charged
: and so on, as indicated in the table above. What is the maximum annual
: bonus, in dollars?
: (A) $100
: (B) $150
: (C) $200
: (D) $250

: 答案是B 不是應該10000*2.0% = 200嗎
1000*0.5% + 2000*1% + 3000*1.5% +4000*2% = 150
