A tank initially contains 50 liters of water. A hose adds water to the tank at a rate of 2 liters per minute. Write a linear equation for the amount of water in the tank, W, liters in terms of t, minutes. Then use your equation to find how much water is in the tank after 20 minutes.

50+2(x)=L water in tank
50+2(20)=L water in tank
50+40=90L water in tank
