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? | [
"$0",
"$8,000",
"$6,000",

Gross Profit = (Selling Price - Original Price)*(# of Items Sold)
So lets figure out what the Gross Profit for 1995:
GP1995 = (40-20)*(1000) = 20000
And the Gross Profit for 1996:
