To obtain the minute, when both containers will have the same amount of water, we use the equation ;
Let the number of minute = m
Container A :
- Initial Volume = 300
- Fill rate = 5 ltr/min
- Amount of water after m, minutes = 300 + 5m - - (1)
Container B :
- Initial volume = 700
- Drain rate = 6 ltr/ min
- Amount of water after, m , minutes = 700 - 6m - - (2)
Time when both A and B will have the same amount of water :
- Equation (1) = Equation (2)
- 300 + 5m = 700 - 6m
Hence, the required equation is : 300 + 5m = 700 - 6m

Answer:
5 weeks
$175
Step-by-step explanation:
Bill owes his mother $300 and plans to pay her $25 every week.
Therefore, after w weeks he has to give her mother more C = 300 - 25w, amount of money.
Steve owes his mother $550 and plans to pay her $75 every week.
Therefore, after w weeks he has to give her mother more C = 550 - 75w, amount of money.
If after w weeks they both will owe their mother the same amount of money, then
300 - 25w = 550 - 75w
⇒ w = 5 weeks. (Answer)
Now, the amount of money will be $(300 - 25 × 5) = $175. (Answer)
