Working together at their respective constant rates, Machine A and Machine B can produce 1,800 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 1,800 unit total would it produce?	Choose the correct choice from the following choices:  A) 25  B) 33  C) 30  D) 67  E) 75
1/A+1/B= 1/T   1/A +1/12= 1/8 (50% more of 8 is 12)   1/A= 1/24   Machine A can produce 1800 units in 24 hrs, so it can produce  1800*8/24=

600 units is 8 hrs.   600 is 30% of 1800.   30 is the answer
