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? | [
"25",
"30",
"75",
"67"
] | B | 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.
