Math Problem Statement
United Research Associates (URA) had received a contract to produce two units of a new cruise missile guidance control. The first unit took 5,000 hours to complete and cost $40,000 in materials and equipment usage. The second took 4,750 hours and cost $34,000 in materials and equipment usage. Labor cost is charged at $20 per hour. The company expects “learning” to occur relative to labor and also the pricing of parts from suppliers.
The prime contractor has now approached URA and asked to submit a bid for the cost of producing another 20 guidance controls. What will the last unit cost to build? use Exhibit 4A.5 - Improvement Curves: Table of Unit Values
