Answer:
W = 30T + 500
Step-by-step explanation:
We are given that water is added in the pond at a rate of 30 liters per minute and there are total 500 liters in the pond to start.
So assuming W to be the amount of water in the pond (in liters) and T to be the the number of minutes that water has been added, we can write an equation:
W = 30T + 500
(W on the y-axis and T on the x axis)
