This question is extra credit becaause she has not taught it to us. thanks so much for helping! Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Add the rates of processing to get the rate of both together
First machine's rate:
( 1 batch ) / ( 18 min )
Second machine's rate:
( 1 batch ) / ( 12 min )
Let = minutes to process with both machines
It takes both machines together 7.2 minutes
