In graph, it seems that (12,16) is solution of system of equations. Check if it is indeed the solution.
As the point satisfies both equations, it is solution of system of equations.
Thus, 12 small candles and 16 large candles should be sold.
Conclusion:
Thus, 12 small candles and 16 large candles should be sold.
