supply demand question beginner
The new "equilibrium" would have been at a lower price on the assumption that the firm has full Monopoly over the market (and hence cannot instead just compete with some other firm for a larger share of market demand) and demand remains constant. 

Moreover unless you know about the elasticity of demand (how sensitive people's wish to buy is with regards to commodity price) you cannot be certain if selling a significantly larger amount at a slightly smaller price might in totality fetch the producer a larger sum of money.
