Amount raised in past by Volleyball team = $9
Revenue generated per car = $4
Let,
c be the number of cars.
T be be funds raised
T = 4c + 9 Eqn 1
Amount raised by Wrestling team = $101
Revenue generated per car = $3
T = 3c+101 Eqn 2
For same amount;
Eqn 1 = Eqn 2
After washing 92 cars, both teams will have same amount.
Putting c=92 in Eqn 1 and 2
The total will be $377.
