Given:

To Find:

An inequality to find the most money that can be used for other spending.

Solution:

The required inequality is .

Explanation:

Let x denote the money I can spend for other purposes. Then x has to be less than or equal to the left over money of my savings after the CD and card are bought.

The CD and card together cost me $12.99 + 2.50 = $15.49

My savings are $25.

So, after buying the CD and card, I'll be left with $25 - 15.49 = $9.51

Thus all my other expenditure denoted by x has to be less than or equal to 9.51.

The required inequality is .
