Question

Mario is playing an online puzzle game. He has 50 points and earns 3 points for each puzzle he solves correctly. He will advance to the intermediate level if his score is over 80 points. Which inequality can Mario use to find how many more puzzles he must solve to advance to the intermediate level? O A. 3x + 50 > 80 O B. 3x+ 50 < 80 O c. 50x+ 3 > 80 D. 3x + 80 < 50

Answer 1

A. 3x + 50 > 80

Step-by-step explanation:

The number of points Mario already has = 50.

For each puzzle solved, Mario gets 3 points.

Therefore, if Mario solves x puzzles, he gets an additional point of 3x.

The total number of points that Mario has = 3x+50.

For Mario to advance to the intermediate level, he must have over 80 points.

Therefore, the inequality that Mario can use to find how many more puzzles he must solve will be:

`3x+50>80`
