Johnson industries received a contract to develop and produce four high-intensity long-distance receiverttransmitters for cellular telephones. The first took 2,000 labor hours and $39,000 worth of purchased and marufactured parts; the second took 1,220 labor hours and $27,690 in parts; the third took 970 iabor hours and $23,400 in parts; and the fourth took 720 labor hours and $19.110 in parts. The company expects "leaming" to occur relotive to labor and also relative to the pricing of parts from suppliers. Johnson was asked to bid on a followion contract for another dozen receiveritransmitter units. knoring any forgetting factor effects, What should Johnson estimate time and parts costs to be for the dozen units? (Hint. These are two learning curves-one for labor and one for ports) Use Exhibit 4A G. a. How many labor hours should Johnson estimate are needed for the additional 12 units? Note: Round your answer to the nearest whole number. b. How much should Johnson estimate the parts cost will be for the odditional 12 units? Note: Round your answer to the nearest dollar amount
