A unique real-world problem that could be solved with this inequality is determining the number of hours a person can work to earn a certain amount of money.
For example, let's say you are paid $18 per hour, and you want to ensure that you earn at least $11. To find the maximum number of hours you can work to reach that earning, you can use the inequality 4x + 7 < 18.
To solve this inequality, you would subtract 7 from both sides: 4x < 11. Then, you would divide both sides by 4 to isolate the variable: x < 11/4.
To communicate the solution to this real-world problem clearly, you would explain that the maximum number of hours you can work is 11/4 hours, which is equivalent to 2 hours and 45 minutes. This means that if you work for 2 hours and 45 minutes at a rate of $18 per hour, you will earn at least $11.
4x + 7 < 18. I was buying pretzels for the 4 people in my house including me. Can you solve this inequality? First i subtracted 7 from both sides. 4x + 7 -𝟕 < 18 -𝟕 to get 4x + < 11 Then I Divided both sides by the same factor. 4x < 11 __4x__ < __11__ 4 4 After you finish the rest, you get x < _11_ 4
provide a unique real-world problem that could be solved with their inequality. Explain what if would look like to communicate the solution to your real-world problem clearly.
