Salem Corp. contracted for a specialized production machine from Quindo Industries, a tool company. The contract specified a price equal to "115 percent of production cost." A sales executive at the Quindo told Salem's management that the approximate price of the machine would be $1,725,000 based on the following estimates:
Direct material cost $500,000
Direct labor cost 400,000
Manufacturing overhead ( applied based on machine time) 600,000
Markup 225,000
Estimated price to $1,725,000

Two months later, Quindo Industries delivered the completed machinery, configured and manufactured as per the contract. However, the accompanying invoice caught Salem's executives by surprise. The invoice provided the following:

Direct material cost $658,000 Direct labor cost 625,000
Manufacturing overhead (applied based on machine time) 640,000
Markup 288,450 Estimated price to Salem $2,211,450
