We can solve this problem by calculating how many ounces of coffee the patient drinks each day, and then calculating how many ounces they are allowed to drink. Since we are told they need to cut back 60%, this means they are allowed to drink 100% - 60% = 40% of their current daily intake.
Step 1: Calculate the total number of ounces of coffee the patient currently drinks.
5 cups × 12 ounces = 60 ounces
Step 2: Use the percent formula to calculate how much of the current 60 ounces the patient is allowed to drink. The percent formula is below:
