Understanding the Problem

Clarissa has a budget of $\$1,200$ a month to spend on rent and food. She has already spent $\$928$ this month. To determine the amount she can still spend and remain within her budget, we need to set up an inequality.

Setting Up the Inequality

Let $x$ be the amount Clarissa can still spend this month. Since she has already spent $\$928$ , the total amount she can spend is the difference between her budget and the amount she has already spent. This can be represented as:

1200 - 928 \leq x

Simplifying the Inequality

To simplify the inequality, we can subtract $928$ from both sides:

272 \leq x

Interpreting the Inequality

The inequality $272 \leq x$ means that the amount Clarissa can still spend this month is greater than or equal to $\$272$ . This is the amount she can spend and remain within her budget.

Conclusion

In conclusion, the inequality that represents the amount Clarissa can still spend this month and remain within her budget is $272 \leq x$ . This inequality ensures that Clarissa does not exceed her budget of $\$1,200$ .

Example Use Case

Suppose Clarissa wants to spend $\$300$ on food this month. To determine if she can still spend within her budget, we can substitute $x = 300$ into the inequality:

272 \leq 300

Since $272 \leq 300$ is true, Clarissa can still spend $\$300$ on food this month and remain within her budget.

Tips and Variations

If Clarissa wants to spend more than $\$300$ on food, we can substitute $x = 300 + y$ into the inequality, where $y$ is the additional amount she wants to spend.
If Clarissa wants to spend less than $\$300$ on food, we can substitute $x = 300 - y$ into the inequality, where $y$ is the amount she wants to save.

Common Mistakes

Not considering the amount Clarissa has already spent when setting up the inequality.
Not simplifying the inequality to its simplest form.
Not interpreting the inequality correctly.

Conclusion

$In conclusion, the inequality $272 \leq x$ represents the amount Clarissa can still spend this month and remain within her budget. This inequality ensures that Clarissa does not exceed her budget of $\$1,200$.<br/> **Clarissa's Budget Inequality: Q&A**$
