Kayla is purchasing 5 candles for x dollars each and 5 candle holders for $3.50 each. Kayla paid a total of $27.50. Before tax, what is the cost per candle?

A. $2.00
B. $4.80
C. $6.20
D. $9.00

Let the cost per candle be x dollars each.

So, the total cost of candles = 5x and the total cost of candle holders = 5 x $3.50 = $17.50

Therefore, the total cost before tax = 5x + $17.50 = $27.50

5x = $27.50 - $17.50
5x = $10
x = $2

Therefore, the cost per candle is $2 each, which corresponds to option A. $2.00.
