Answer:
He drank 14.875 gallons of water per month.
Step-by-step explanation:
How many fluid ounces did he drink in total?
He drank 80 fluid ounces of water per day during the first 3 weeks.
64 fluid ounces of water per day for the next 3 weeks
For the last 2 weeks, he drank 56 fluid ounces of water per day
Each week has 7 days. So
T = 3*7*80 + 3*7*64 + 2*7*56 = 3808
He drank 3808 fluid ounces of water.
How many gallons did he drink?
Each fluid ounce has 0.0078125 gallons.
3808*0.0078125 = 29.75
He drank 29.75 gallons of water in two months. How much did he drink per month?
29.75/2 = 14.875
He drank 14.875 gallons of water per month.
