16 large candles and 12 small candles were sold.
Step-by-step explanation:
Given,
Worth of candles sold = $144
Total candles sold = 28
Cost of each large candle = $6
Cost of each small candle = $4
Let,
x be the number of large candles sold.
y be the number of small candles sold.
According to given statement;
x+y=28 Eqn 1
6x+4y=144 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 2
Putting x=16 in Eqn 1
16 large candles and 12 small candles were sold.
