Wilson Partners manufactures thermocouples for remote temperature monitoring of electronics applications. The current system has a fixed cost of $400,000 per year and a variable cost of $10 per unit. Wilson sells the units for $14 each. A newly proposed system will add on-board features that allow the revenue to increase to $16 per unit, but the fixed cost will now be $600,000 per year. The variable cost of the new system will be based on a $48 per hour rate with 0.2 hour dedicated to produce each unit.
