Answer:
J; 250 + 50x > 330 + 30x
Step-by-step explanation:
Since we don't have to worry about formatting the numbers to slope-intercept form, we can start the process of elimination.
First, we can disregard G and H because both have the x in the wrong place:
—> F 270 + 50x ≥ 330 + 30x
—> G 270x + 50 > 330x + 30
—> H 270x + 50 < 330x +30
—> J 270 + 50x > 330 + 30x
We're looking for <em>270 + 50x > 330 + 30x</em>.
Next, we determine which symbols are correct. Since the question is only asking for when American Airlines would be more expensive, not when it would be just as much or more, we can get rid of F.
—> F 270 + 50x ≥ 330 + 30x
—> J 270 +50x > 330 + 30x
We finally have our answer, J.
