can somebody please help me with this question??...A copy machine makes 60 copies per minute. a second machine makes 80 copies per minute. the second machine starts making copies 2 minutes after the first machine starts. both machines stop making copies 8 minutes after the first machine started. together, the 2 machines made how many copies?
the first machine runs for 8 minutes the second machine runs for 6 minutes (since the first one got a 2 min head start)
first one makes 60 copies per min, so how many copies can the first one make in 8 min?
the second one makes 80 copies per min and runs for 6 min so it makes a total of _____ copies
add the two totals
that's your final answer
you're welcome
