Acopy 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?

m 960 copies

Step-by-step explanation:

The first maching was working 8 minutes this means that it produced

60 copies /minute* 8minutes = 480 copies

teh second maching was operated during 6 minutes so it made

80 copies/minute *6 minutes = 480 copies

The total copies from the two machines were 960.

2/3=4/6 and that's 4 times 1/6. So the answer is 100% times 4 which is 400%
