标题: GWD3-37? 查过讨论还是搞不明白

Q37: B

In 1995 a certain store had 1,800 tools in stock that had been purchased for $30 each. If 1,000 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. $6,000

C. $8,000

D. $32,000

E. $40,000

到底是哪个和哪个做比较？ｇｒｏｓｓ　ｐｒｏｆｉｔ是指什么？这题不难把，可是愣没算出答案.

(50-30)*800-(40-30)*1000=6000

我看过讨论是这么做的，可我不理解为什么要这么算，能说明一下gross profit是什么吗？而且没有明确指出和哪个1995的相比呀。1996年卖的800*50 不比1995年卖的18000*30的大呀
