to dealers for each modification completed. Honda is trying to establish a fair amount of compensation to pay dealers and has decide to choose a number of randomly selected mechanics and observe their performance and learning rate. Analysis demonstrated that th average learning rate was $90$ percent, and Honda then decided to pay a $$60$ fee for each repair $(3$ hours $$$$20$ per flat$-$rate hour$).$

Southwest Honda, Incorporated, has complained to Honda Motor Company about the fee. Six mechanics, working independently, have completed two modifications each. All took $9$ hours, on average, to do the first unit and $8\mathrm{.}10$ hours to do the second. Southwest refuses to do any more unless Honda allows at least $360$ hours. The dealership expects to perform the modification to approximately $60$ vehicles. Use Exhibit $6\mathrm{.}5.$

What is your opinion of Honda's allowed rate and the mechanics' performance?
