The key club made $192 at their candle sale.They sold round candles for $4 and square candles for $6. if they sold twice as many square candles as round ones, how many of each type of candle did the key club sell?
Answer provided by our tutors
Let 'x' represent the number of round candles, then '2x' represents the number of square candles:
192=4x+6(2x)
x=12
12*2=24
So 12 round candles and 24 square candles were sold.
