A copy machine makes 60 copies per minute. A second copy 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?

1st copier = 60 x 8 =480 copies

2nd copier = 80 x 6 =480 copies

480 + 480 = 960 copies made by both copiers after 8 minutes.
