You can put this solution on YOUR website! At the beginning of a minor league baseball game, the hot dog vendor had 200 hot dogs selling at $4 each. At the beginning of the eighth inning, he lowered the price to $2 to clear his remaining inventory. If his hot dog receipts for the day total $640, how many hot dogs did he well at each price.
-------
h + h' = 200
4h + 2h' = 640
----------
h + h' = 200
2h + h' = 320
----------------------
h = 120 (# sold at $4)
-----
Solve for h'::
h' = 200 - 120 = 80 (# sold at $2)
