Based on the following assumptions and financial information, select all the true statements Year 1 Year 2 Year 3 Year 4 Production in units 4,000 6,000 8,000 4,000 Sales in units 4,000 3,000 3,000 11,000 (1) Selling price per unit, variable cost per unit, and total fixed costs do not change during the four years.
