can someone tell me why the answer for this is B???
Q37:
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

[clbb]

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

=16000-10000

=6000
