Question

the following expression models the total money earned by setting up a good stall at a fun fair where x represents the number of cheeseburgers sold

Answer 1

Option D is the right answer

In the above expression, $\frac{60x}{x+3}$ + 10, the constant 10 represents the total money earned by setting up a food stall (Oprion D). This is justified because if there is no sales, x = 0, and from the expression, when x = 0, total money earned = 10.
