Janine is considering buying a water filter and a reusable water bottle rather than buying bottled water. Here are the facts:

Right now, Janine drinks 3 bottles of water a day, at 16.9 ounces each. She usually buys 24-packs of 16.9 ounce bottles for $3.89.

A reusable water bottle costs about $10, which lasts forever (until you lose it). A water filter costs about $28 and includes one filter cartridge. Refills cost $33 for a 3-pack. Each filter filters up to 100 gallons (378 liters).
