An electronics firm is currently manufacturing an item that has a variable cost of $\mathrm{.}55$ per unit and a selling price of $1\mathrm{.}15$ per unit. Fixed costs are $$14000.$ Current volume is $30000$ units. The firm can substantially improve the product quality by adding a new piece of equipment at an additional fixed cost of $$5600.$ Variable cost would increase to $$\mathrm{.}60$ and the selling price would be revised to $$1\mathrm{.}35$ with the expectation that the volume would be $50000$ units as a result of a$$ higher$-$quality product. Part $2$ If the firm does not add new$$ equipment, its profit will be$=4000$ dollars $($round your response to the nearest whole number and include a minus sign if the profit is$$ negative$).$ Part $3$ If the firm does add new$$ equipment, its profit will be$=7900$ dollars $($round your response to the nearest whole number and include a minus sign if the profit is$$ negative$).$
