The doctor tells the patient to cut back on coffee. The patient usually has four 8 oz cups of coffee per day. If the doctor told him to cut back by 25%, how many ounces of coffee can the patient have each day?

The patient can still have 3. Simply find out how many ounces he drinks first which is 32 oz. Now that you know that all you have to do is figure out how much 25% is and for that just multiply 32*.25 and that should equal 8. If he drinks 4 8 ounces a day then if he can't drink 8 ounces it makes it 28 which is 3.
