12/8-7/8 is 5/8 so the answer is 5/8

Well slope Int form is

y= mX +b

So we multiply -4/5 to both "x" and -5

y+5=-4/5x+4

subtract 5 on both sides

y= -4/5x-1

**The patient can have 204.8 ounce cups of coffee every day.**

**Step-by-step explanation:**

Initial consumption limit of the coffee by the patient- 512-ounce cups

Doctor recommendation-60% cut back in the coffee consumption

Thus according to the doctor's recommendation, if the patient needs to cut back 60% of the coffee consumption, then he is only to consume remaining (100-60)= 40% of his daily consumption.

Total daily consumption he can take= 40% of initial consumption

= (40/100) *512 ounces

= 204.8 ounces of coffee

**Hence, the patient needs to take only 204.8 ounces of coffee complying by the Doctor’s recommendation.
