Final answer:
The concessionaire pays the vendor $50 per game for selling hot dogs at $4.50 each, resulting in a profit of $46.50 per hot dog.
Step-by-step explanation:
In this scenario, the concessionaire pays the vendor $50 per game for selling hot dogs at $4.50 each. To determine the profit per hot dog, we need to subtract the cost per hot dog from the selling price. So, the profit per hot dog is $4.50 - $50 = $-45.50. Therefore, the statement is false.
