If the objective coefficient for $S$ is $7$ instead of $10,$ will the optimal solution remain the same? How about the profit?

The optimal solution will change, but the profit will remain the same

The optimal solution will change, but the profit will change to $$6048$

The optimal solution wif remain the same, but the profit will change to $$6048$

The optimal solution will remain the same, and the profit will remain the same
