We will determine the inequality as follows:
*First: We will determine the interception point of the two equations, that is:
So:
Now, we replace x = 10 on any of the two equations:
So, the interception point is located at (10, 85).
*Second: We determine the inequality that represents the problem, that is:
[This is overall, the second equation represents greater cost].
*Third: The least number of medals that cab ve ordered so company's A cost is less than company's B cost is 10 medals.
