In 1995 a certain store had ,2000 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?  Select the correct option:
A) $0 B) $6,000 C) $8,000 D) $32,000 E) $10,000
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 = (40-30)*(1000)= 
<gadget id="calculator">(40-30)*(1000)</gadget>
<output>10_000</output>
10000   And the Gross Profit for 1996:   GP1996= (50-30)*(1000)= 
<gadget id="calculator">(50-30)*(1000)</gadget>
<output>20_000</output>
20000   So the difference would be:   20000-10000= 
<gadget id="calculator">20000-10000</gadget>
<output>10_000</output>
10000   ANSW$10,000R: $10,000.
