Due to load shedding, the country suddenly struggles with water too. You decide to install a $5000$ litres JoJo tank at your house. The municipal truck refills your JoJo tank with water at a cost whenever you call for them. But this one time, the municipal truck only fills $17/20$ of your JoJo tank. You notice this and you contact the municipality, they then agree to refund you the sum of money for your outstanding litres of water. If they charged you R$411\mathrm{.}98$ for $5000$ litres of water, then calculate the amount of money they owe you in Rands for the outstanding litres of water.
