3 Behnaz makes candles.
She has 6.3 kilograms of wax and uses it all to make candles.
Each candle Behnaz makes uses 210 grams of wax.
Behnaz sells \(\dfrac{2}{5}\) of the candles for \(\$\)13 each.
She then reduces this price by 20% and sells the rest of the candles.
Work out the total amount of money Behnaz gets by selling all the candles she made.
