Answer:
24
Explanation:
Start by finding the unit price. Unit price is the term for finding the price of one unit of an item, often used in word problems. We find this by dividing the cost of an item after a certain amount is sold, by that amount.
Now, we know the unit price is 12. Divide the end value of everything you sold by the unit price, 12.
Therefore, you sold 24 candles.
