Answer:
10 | 4880
30 | 4640
50 | 4400
Explanation:
The initial amount of water is 5000 gallons and it is draining at a rate of 12 gallons per minute; therefore, the equation describing the amount y left and the number of minutes x elapsed is

With the equation in hand, we now evaluate it at x = 10, 30, and 50 to create the table.

at x = 30 we have

and at x = 50 we have

Hence, the table
10 | 4880
30 | 4640
50 | 4400
