The school cafeteria has 500 water bottles in stock and sells a total of 60 water bottles per day. Write a function rule to represent this situation using w for the total amount of water bottles in stock at the end of d days

W=500-60d

Step-by-step explanation:

W=the remain water bottles

500=total water bottles

60water bottles times d=total water bottles at the end of days
