Answer:

After 30.2 minutes, the two pools will have the same amount of water.

Explanation:

(a)The general structure of the equation is that of a linear function:

[tex]y=mx+b[/tex]

(b)

Variable Definition

Let the amount of water in the pool after m minutes = y

Let the number of minutes the pool has been drained = m

Left-Side Expression:

Mr Zoetrope's pool has 10,858 gallons and is draining 150 gallons per minute.

[tex]\implies y=10,858-150m[/tex]

Right-Side Expression:

Mrs Homer's pool has 9,650 gallons and is draining 110 gallons per minute.

[tex]\implies y=9650-110m[/tex]

The equation

[tex]10858-150m=9650-110m[/tex]

We solve for m.

[tex]\begin{gathered} 10,858-9650=150m-110m \\ 1208=40m \\ m=30.2 \end{gathered}[/tex]

After 30.2 minutes, the two pools will have the same amount of water.
