# Systems of linear inequalities word problems — Harder example

Watch Sal work through a harder Systems of linear inequalities word problem.

## Want to join the conversation?

• So ' at least' means 'no less than' and ' equal to or more than'?
• Yes. At least does mean 'greater than or equal to' or 'no less than'. x is at least 10, is x ≥ 10
• is there an easy way or one or two clues to mastering this topic? My SAT is next week and I really want to master this but it is kind of hard. Especially ones involving graphs.
• what is the best way to approach and tackle word problems,am poor at it.
• I'd do what Sal does: go and underline the important parts of the word problem. After you find the key parts of the problem, use that simpler information to solve. Hope this helps. :)
• I want to try the SAT in October and these courses are making me feel a little more confident, I also realized that graphs are my weak point
• If it said "up to 24" how come you use the greater than/equal to sign? Wouldn't 24 be the maximum? Thanks
• actually, you would use the less than/equal to sign. you might have gotten confused with one of the incorrect answers on the bottom. hope this helped :)
• cooked in seconds ezzzz.....
• at
I did not understand why c>or equal to a
• Because in the question he said that the one box must have ( at least as many cell phones "c" as accessories "a" ) ..
And ( At least " > " as many " = " ) means > or equal
