Texas 8th Grade Math Question of the Day

Break-even occurs when $y$-intercepts match, so the plans never break even.

The plans break even at $x=12$, but the common cost is 24.

The plans break even at $x=12$ with a common cost of 30; this is where the graphs intersect.

Break-even happens when both slopes are 2, so break-even is at $x=2$.
