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 $50 each and the remaining 800 were sold in 1996 for $60 each, how many greater was the gross profit on the tools sold in 1996 than the gross profit on those sold in 1995?  Choose the correct answer:
A) $0	B) $4,000	C) $8,000	D) $32,000	E) $40,000
The keyword here isGross Profit:   Gross Profit = (Selling Price - Original Price)*(# of Items Sold)   So lets figure out what the Gross Profit for 1995:   GP1995 = (50-30)*(1000)=

<output>20_000</output>
20000   And the Gross Profit for 1996:   GP1996= (60-30)*(800)= 
<gadget id="calculator">(60-30)*(800)</gadget>
<output>24_000</output>
24000   So the difference would be:   24000-20000= 
<gadget id="calculator">24000-20000</gadget>
<output>4_000</output>
