Owners of a recreation area are filling a small pond with water. They are adding water at a rate of \( 35 \) liters per minute. There are \( 600 \) liters in the pond to start. Let \( W \) represent the total amount of water in the pond (in liters), and let \( T \) represent the total number of minutes that water has been added. Write an equation relating \( W \) to \( T \) . Then use this equation to find the total amount of water after \( 19 \) minutes.
Equation: \( \square \)
Total amount of water after \( 19 \) minutes: \( \square \) liters
