Answer:
In the expression
what the constant term -10 represents is;
A. The constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold
Explanation:
Whereby the expression is as given in a similar question which is presented as follows;

Where the expression represents the total money earned when a food stall is set up at a fair where 'x' stands for the number of cheeseburgers sold
Then when no cheeseburger were sold, x = 0, such at the start just after setting up the food stall, we then have;

Therefore, the money earned at the start = -10
∴ The money spent at the start = 10
Therefore, the constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold.
