The information that we need to answer this Question: is Written in Bold Letters
1. Amount of Water Drunk by Janine in a day= 4 × 16.9 Ounces= 67.6 Ounces= Approximately 2 Liter
2. Cost of 24-packs of 16.9 ounce bottles = $3.89
Cost of 4×6 packs of 16.9 ounce bottles =$3.89
Cost of 2 liter or 4 packs of 16.9 ounce bottles =$
3. Cost of Reusable water bottle = $ 10
4. Time for which a reusable water bottle last= Infinitely
5. Cost of a faucet-mounted filter= $ 28
Cost of Refilling for a 3 pack filter=$ 33
So, Cost of Refilling a 1 pack filter= $11
1 filter will filter approximately =100 gallons of water=378 Liters
6. Cost of a water filter pitcher= $ 22
Now, coming to second part ,whether buying a water filter and a reusable water bottle rather than buying bottled water will save her money?
→Total cost of water filter and a reusable water bottle = $28+$10+ $ (33÷3) ×(Number of times She refills the 3 filter pack)= $ 38 + $11 n
For, 1 water filter and a reusable water bottle total money spent = $ 49
→As the filter contains , 378 Liters of water, and Janine drinks Approx 2 liters of water daily, so 1 filter will last for 189 days.
→1 Liter = 33.81 Ounce
→Cost of 378 liters of water== $ 122.535
So, We can Surely say that , buying a water filter and a reusable water bottle rather than buying bottled water will save Janine money.
