Total Cost must be less than or equal to her past saving plus her future savings.

Let her future savings be the variable S.

Then we have a simple inequality:

So we know that Chantal's future savings must be greater than or equal to 23 dollars.

In other words, 23 dollars is the least amount she must save to be able to purchase the shoes.

There are other non-algebraic ways to look at this problem,

but this way seemed the most intuitive to me.

One simple way is just to find the difference between what she needs, and what she has.

Thus she would need at least 23 dollars to buy the shoes.

Of course if she has to pay sales tax on the shoes,

the problem gets a little more difficult!

I hope this helps! Keep practicing! :)
