Answer: [tex]W\text{ = 30T + 600 \lparen equation\rparen}[/tex]
See graph below
Explanation:
Given:
Rate water is added = 30 l/min
The initial amount in the pond = 600l
To find:
The equation relating the amount of water in the pond to the number of minutes the water is being added
W = amount of water in the pond
T = number of minutes that water has been added
Amount of water in the pond = rate water is added (number of minutes that water has been added) + the initial amount in the pond
[tex]\begin{gathered} W\text{ = 30\lparen T\rparen + 600} \\ W\text{ = 30T + 600 \lparen equation\rparen} \end{gathered}[/tex]
Graphing the equation:
To graph the equation, we will assign values to T
when T = 0, W = 600
when T = 2, W = 660
when T = 4, W = 720
when T = 6, W = 780
