Answer:
$684
Explanation:
Let number of small candles be x
let number of big candles be y
y - 27 = x [they had sold 27 more big candles than small candles. ]
4.5y - 234 = 3x [They made $234 more from the sale of big candles than they did from the small candles]
Let's replace first equation in 2nd and get y:

and x = 102 - 27 = 75
Amount made from small candles = 75 * 3 = 225
Amount made from big candles = 4.5 * 102 = 459
Total = $684
