17. Your goal is to save at least $360.00 over the next 6 weeks. How much money must you save each week in order to meet that go
OLga [1]
<h2>Answer </h2>

D. 6x>_360; x>_60

<h2>Explanation</h2>

Let x be amount you will save each weeks

Since we know that you are saving over a period of 6 weeks, you will save 6x.

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 \geq (greater on equal than)

Now we can combine our tow parts using the inequality symbol:

6x\geq 360

To simplify divide both sides by 6:

\frac{6}{6} x\geq \frac{360}{6}

x\geq 60

You need to save at least $60 per week, so the correct answer is D. 6x>_360; x>_60
