Answer:

34 gallons still remain after 8 minutes.

Step-by-step explanation:

Variable x = gallons of water after 8 mins

2 gallons = 1 min

x gallons = 8 mins

Set up an equation:

2/1 = x/8

Cross multiply:

2 × 8 = 1 × x

16 = x

16 gallons of water are <em>draine</em><em>d</em><em> </em>after 8 minutes.

Find the difference:

50 - 16 = 34

34 gallons still <em>remain</em> after 8 minutes.

Answer:

34 gallons

Step-by-step explanation:

Water in tank = starting amount - rate * time

water in tank   = 50 - 2 * time

Let the time = 8 minutes

water in tank   = 50 - 2 * 8

                        = 50 - 16

                        = 34
