Final answer:
The constant term in the expression represents the cost of setting up the food stall even if no cheeseburgers were sold.
Step-by-step explanation:
The constant term in the expression (60x/x+3-10) represents the cost of setting up the food stall even if no cheeseburgers were sold. It is the value that remains constant regardless of the number of cheeseburgers sold. In this case, the constant term is -10, which represents the cost of setting up the food stall.
