A food truck's daily cost is $y = 150 + 4x$ and its revenue is $y = 9x$, where $x$ is the number of meals sold. What does the intersection point of these two lines represent?

The maximum number of meals sold

The break-even point where cost equals revenue

The point where revenue exceeds cost by the most

The minimum number of meals needed to open

Plan A charges $y = 30 + 5x$ dollars and Plan B charges $y = 10 + 8x$ dollars, where $x$ is months. At the intersection point $(\,x, y\,) = (\,\ldots\,)$, what is true about the two plans?

Plan A is always cheaper than Plan B

Plan B is always cheaper than Plan A

Both plans cost exactly the same amount

The plans never cost the same amount
