Lesson 4: One-step inequalities

# One-step inequality word problem

Inequalities are more than abstract concepts and exercises. They help solve real life problems. Here's an example. Created by Sal Khan and Monterey Institute for Technology and Education.

• Isn't the limit \$1000? So we can be equal to or less than \$1000. Correct me if I'm wrong.
• I'm pretty sure it just says that because above it it already states that it has to be less than \$1,000

• ? This is the most hardest unit for me so far
• i want to know how you figured that out because i am sooooo confused
• how would you write this sentence into an inequality:

"Gary watches at most 2 hours of television on a weekday"?
• Hint: "at most 2 hours" means gary can't watch any more than 2 hours. Which inequality do you think would match that situation? Give it a try.
• a basic question; whats a patio?
• I believe a patio is kind of like a porch.
• Does anyone know of a shop that would sell a third of a tile? Surely the correct answer is 333 tiles, 333 sq ft.
• i know, right? but you CAN ask for a third in most places
• how did you get 333 1/3 at in the video
• you divide 1000 by 3
• shouldn't the patio be <= 333.3 sqft?
• these make me so confused

• What is confusing? Have you gotten one-step equalities down well? One step inequalities is just an extension of one-step equalities with the caveat that If you divide or multiply by a negative, you have to flip the inequality sign.
