Step 1

To convert the given word problem into an equation for the unknown x (theamount of skimmed milk required )

Step 2

The mixture contains x ounces of skimmed milk with 4 ounces of table cream, so totally 4+x ounces. We need the fat content of this mixture to be 3.25%.

Step 3

To set up the equation for x, we work out the fat content of the skimmed milk and the table cream sepa...
