Answer:
The store sell 12 large candles
Step-by-step explanation:
Let x be the no. of small candles
Cost of 1 small candle = $10.98
Cost of x small candles = 10.98x
Let y be the no. of large candles
Cost of 1 large candle = $27.98
Cost of y large candles = 27.98y
We are given that a candle store received $423.60 for selling 20 candles.
So,
Plot these lines on graph
x+y=20 --- Green
10.98x+27.98y=423.60 --- Blue
Intersection point provides solution
So,Intersection point = (8,12)
So, y=12
Hence The store sell 12 large candles
