Westside produces pillows with monthly unit sales and costs given as:

Unit Sales: 4000 units

Price: $10.00 per unit

Variable costs: $5.50 per unit

Fixed costs: $15,000

Given the production capacity of 4,000, the company has to install another workstation at a monthly cost of $800 (assume no change of variable costs). The new station raises plant capacity by 1,000 units. By what % would sales have to increase to justify a 5% price cut?
