Question

The cost of hosting a dinner in a particular restaurant is given by y = 18.5x + 250, where x is the number of people at the dinner and y is dollars. What is the y-intercept of this function? What does it mean in the context of the problem?

Answer 1

The y-intercept is at (0, 250)

It means that there is a flat fee of $250 when hosting a dinner

It represents a $250 flat fee because it is automatically charged, no matter how many attend the dinner
