The 60955-SQ company manufactures a product that sells for $25 per unit. At present, the product is manufactured in a factory that mostly uses direct labor workers. The variable expenses are $15 per unit and the direct labor cost makes up 60% of variable expenses Last year, the 60955-SQ company sold 34.000 units of its product and provided the following results: Sales (34,000 balls) $850,000 Variable expenses 510,000 Contribution margin 340,000 Fixed expenses 212,000 Net operating income $ 128,000 The 60955-SQ company considers building a new and high-tech factory. The new factory would reduce variable expenses per unit by 40%, but would double the company's fixed expenses per year due to investment in fixed assets.
