Question 1147155: the electrician was upset. she knew that b batteries would power d circuits for 11 days. but she had d+8 circuits to power. how many days would r batteries last? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! b batteries would power d circuits for 11 days.
b/d batteries would power 1 circuit for 11 days
( b/d )*( d + 8 ) batteries would power d + 8 circuits for 11 days
( 1/11 )*( b/d )*( d + 8 ) batteries would power d + 8 circuits for 1 day
1 battery would power d + 8 circuits for 11*( d/b ) / ( d + 8 ) days
r batteries would power d + 8 circuits for 11r*( d/b ) / ( d + 8 ) days
