Question

Fill in the table to fit the verbal description

Answer 1

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

`y=5000-12x`

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

`\begin{gathered} y=5000-12(10)=4880\text{ } \\ \end{gathered}`

at x = 30 we have

`y=5000-12(30)=4640`

and at x = 50 we have

`y=5000-12(50)=4400`

Hence, the table

10 | 4880

30 | 4640

50 | 4400
