What is a real-world inequality math problem?
Here's an example of a real-world inequality math problem:
"Sarah wants to purchase a new smartphone that costs $500. She currently has $300 saved up and plans to save $50 per week from her allowance. If she can only spend the money she has and cannot borrow, how many more weeks will it take for Sarah to afford the smartphone?"
In this problem, the inequality can be represented as:
300 + 50w < 500
Where "w" represents the number of weeks.
By solving this inequality, we can determine the number of weeks Sarah needs to save in order to afford the smartphone.
