Foundation June 2018 Paper 2R Q18
18 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.
