Awater tank already contains 55 gallons of water when baxter begins to fill it. water flows into a tank at a rate of 8 gallons per minute. write an equation to modle this situation. find the volume of water in the tank 25 minutes after baxter begins filling the tank

The answer is : v = 55 + 8m plug in m = 25 v = 55 + 8(25) = 255 25 minutes after baxter begins filling the tank, the volume of water in the tank will be 255 gallons. slope: m = 8 gal/min for every min the water is on, the volume of water in the tank increases by 55 gallons. y-intercept: 55 (0,55) the initial volume of water in the tank was 55 gallons.
