<h2>Answer </h2>
D. 6x>_360; x>_60
<h2>Explanation</h2>Let be amount you will save each weeks
Since we know that you are saving over a period of 6 weeks, you will save .
We also now that your goal is to save at least $360.00 over the period of 6 weeks, so saving more than $360.00 will be very desirable, but the goal is to save $360.00. We can rephrase this as: You need to save $360.00 or more; we can say the same using the inequality symbol (greater on equal than)
Now we can combine our tow parts using the inequality symbol:
To simplify divide both sides by 6:
You need to save at least $60 per week, so the correct answer is D. 6x>_360; x>_60
