For an experiment, Gary makes a hole in the bottom of a bottle full of water and records the amount of water left in the bottle at the end of each minute. He writes the linear model w = -50m + 1200 which describes the amount of water remaining in the water bottle, in w milliliters, after m minutes. Which statement is a correct interpretation of this linear model?

• The water bottle holds 1,200 milliliters of water and loses 50 milliliters per minute.
• The water bottle starts with 1,200 milliliters of water and ends with 50 milliliters of water.
• The water bottle holds 1,200 milliliters of water and loses 1 milliliter of water every 50 minutes.
• The water bottle starts with 1,200 milliliters of water and loses exactly 50 milliliters of water.
