Answer:
The inequality 50 + 3x > 80 can be used by Mario to find how many more puzzles he must solve to advance to the intermediate level.
Step-by-step explanation:
Given that:
Points of Mario in online puzzle game = 50 points
Points earned for each puzzle solved correctly = 3 points
Points needed to advance to intermediate level = over 80 points
Let,
x be the number of puzzles needed to be solved by Mario to advance to next level.
Points Mario already have + Points for each puzzle * Number of puzzles > Points needed to advance
50 + 3x > 80
Hence,
The inequality 50 + 3x > 80 can be used by Mario to find how many more puzzles he must solve to advance to the intermediate level.
