In 1995 a certain store had 1,800 tools in stock that had been purchased for $20 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?
Choose the correct choice from the following answers
A) $0  B) $6,000  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 = (40-20)*(1000)=

<output>20_000</output>
20000   And the Gross Profit for 1996:   GP1996= (50-20)*(800)= 
<gadget id="calculator">(50-20)*(800)</gadget>
<output>24_000</output>
24000   So the difference would be:   24000-20000= 
<gadget id="calculator">24000-20000</gadget>
<output>4_000</output>
