Mr. brown's thrift shop quarter of 2012 profit (in dollars) 1 $9,841.28 2 $8,957.67 3 $7,429.84 4 $11,095.67 what is the difference between the profits mr. brown's store earned in the first quarter and the third quarter?

The difference between the first quarter and the third quarter is $2,411.44 because if you subtract the third quarter profits ($7,429.84 cents) from the first quarter profits (9,841.28 cents), you would get the difference which is $2,411.44 cents. 

Hope this helps :)
