Ch$4$A$-7($Algo$)$

Johnson Industries received a contract to develop and produce four high$-$intensity long$-$distance receiver$/$transmitters for cellular telephones. The first took $2,000$ labor hours and $$39,000$ worth of purchased and manufactured parts; the second took $1,720$ labor hours and $$37,440$ in parts; the third took $1,580$ labor hours and $$36,320$ in parts; and the fourth took $1,445$ labor hours and $$35,190$ in parts. The company expects $$learning$$ to occur relative to labor and also relative to the pricing of parts from suppliers.

Johnson was asked to bid on a follow$-$on contract for another dozen receiver$/$transmitter units. Ignoring any forgetting factor effects, what should Johnson estimate time and parts costs to be for the dozen units? $($Hint: There are two learning curves$$one for labor and one for parts.$)$ Use Exhibit $4$A$\mathrm{.}6.$

How many labor hours should Johnson estimate are needed for the additional $12$ units?

Note: Round your answer to the nearest whole number.

How much should Johnson estimate the parts cost will be for the additional $12$ units?
