Working together at their respective constant rates, Machine A and Machine B can produce 1,500 units in 8 hours. Working alone, Machine B would complete that same output in 50% more time. If Machine A were to work on its own for an 8-hour shift, what percent of the 1,500 unit total would it produce?  Choices:
A) 25	B) 36	C) 30	D) 67	E) 75
1/A+1/B= 1/T   1/A +1/14= 1/8 (50% more of 8 is 14)   1/A= 1/24   Machine A can produce 1500 units in 24 hrs, so it can produce  1500*8/24=

500 units is 8 hrs.   500 is 30% of 1500.   30 is the answer
