Marigold Corp. incurred the following costs to produce $100000$ units:

Variable costs $$440000$

Fixed costs $,800000$

If the item is produced outside, Marigold could use the released production facilities to make another item that would generate $$190000$ of net income. No fixed costs are avoidable. At what unit price would Marigold accept the outside supplier's offer if Marigold wanted to increase net income by $$140000?$

$$3\mathrm{.}90$

$$6\mathrm{.}30$

$$4\mathrm{.}90$
