Question

Using x as the variable, write the equation or inequality that would correctly solve this problem.

Question:
Carmen needs at least 86 points to pass Karissa's score. Karissa has 631 points. How many points does Carmen have?

(there was also some text under the answer box that read: Follow this example: x < 50)

Answer: x = 545 (I think)

Am I right?

Answer 1

Inequalities usually do not have a single number as a solution.
How far behind Karissa is Carmen? 631-x
Now, we know that that's more than 86 points. That is,
631-x >= 86
631-86 >= x
x =< 545

Your answer means that Carmen would tie Karissa's score if she got 545 points.
But we are told that she needs <u>at least</u> 86 points to score <u>more than</u> Karissa.

So, any score less than 545 needs more than 86 points.
