In 1995 a certain store had 1800 tools in stock that had been purchase for $30 each. If 1000 of these tools were sold in 1995 for $40 each and the remaining 800 were sold in 1996 for $50 each , how many greater was the gross profit on the tools sold in 1996 than the gross profit on those sold in 1995？
A. $0
B. $6000
C. $8000
D. $32000
E. $40000

ANS：B

我的想法是
95: purchase 1800*30=54000
95: sold 1000*40=40000
96:sold 800*50=40000

所以我選A.
請問一下我是那裡想錯了呢？
謝謝

95'=1,000x (40-30)=10,000----------(1)
96'=800x (50-30)=16,000------------(2)
(2)-(1)

選 B
