Paula and Sandy were among those people who sold raffle tickets
to raise money for ClubX. If Paula and Sandy sold a total of 100
of the tickets, how many of the tickets did Paula sell ?
1Sandy sold 2/3 as many of the raffle tickets as Paula did
2 Sandy sold 8% of all the raffle tickets sold for Club X
did代表前面做過的動作,
還原後 S sold 2/3 many of the raffle tickets as paula sold 2/3 many of the the raffle tickets
---> S sold 2/3 many of the raffle tickets as pauladid
那就表示 Paula 也和S一樣賣全部票的2/3呀 ,
所以S=(2/3)*100
P也等於(2/3)*100呀
請問那裡錯了呢 ? |
