Working together at their respective constant rates, Machine A and Machine B can produce 1,600 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 1,600 unit total would it produce? Choose the correct choice from the following answers
A) 25
B) 33
C) 50
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 1600 units in 24 hrs, so it can produce 1600*8/24= 533.33 units is 8 hrs.   533.33 is 33.33% of 1600.   33 is the answer
