The three possible sources of energy to meet these needs are electricity, natural gas, and asolar heating unit that can be installed on the roof. The size of the roof limits the largestpossible solar heater to 30 units. Electricity can supply up to 20 units and natural gas cansupply up to 15 units . Electricity needs can be met only by purchasing electricity (at a costof $50 per unit). Both ather energy needs can be met by any source or combination ofsources.

An electronics firm is currently manufacturing an item that has a variable cost of $0.50 per unit and a selling price of $1.10 per unit. Fixed costs are $15,000. Current volume is 30,000 units. The firm can substantially improve the product quality by adding a new piece of equipment at an additional fixed cost of $5,600. Variable cost would increase to $0.65 and the selling price would be revised to $1.30 with the expectation that the volume would be 50,000 units as a result of a higher-quality product. If the firm does not add new equipment, its profit will be =_____ dollars (round your response to the nearest whole number and include a minus sign if the profit is negative).
