Answer:
16v + 24p
Explanation:
Let, the cost of one vanilla candle = v and the cost of one pumpkin candle = p.
Since, there are 4 vanilla candles and 6 pumpkin candles in one set.
Thus,
Cost of 4 vanilla candles = 4v
Cost of 6 pumpkin candles = 6p
Thus, the total cost of both candles in one set = 4v + 6p
Moreover, as there are 4 sets of the candles.
Thus, the total cost of 4 sets = 4 × Cost of one set
i.e. Total cost of 4 sets = 4 × (4v + 6p) = 16v + 24p
Hence, the expression for the total cost of 4 sets is 16v + 24p.
