<PRE><B>Question 702259</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;Total Cost must be less than or equal to her past saving plus her future savings.&lt;br&gt;

Let her future savings be the variable S.&lt;br&gt;

Then we have a simple inequality:&lt;br&gt;

{{{85&lt;=62+S}}}&lt;br&gt;

{{{23&lt;=S}}}&lt;br&gt;

So we know that Chantal&#39;s future savings must be greater than or equal to 23 dollars.&lt;br&gt;

In other words, 23 dollars is the least amount she must save to be able to purchase the shoes.&lt;br&gt;

There are other non-algebraic ways to look at this problem,&lt;br&gt;

but this way seemed the most intuitive to me.&lt;br&gt;

One simple way is just to find the difference between what she needs, and what she has.&lt;br&gt;

{{{85-62=23}}}&lt;br&gt;

Thus she would need at least 23 dollars to buy the shoes.&lt;br&gt;

Of course if she has to pay sales tax on the shoes,&lt;br&gt;

the problem gets a little more difficult!&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
