Machine G and machine B are each used to manufacture 660 sprockets. It takes machine G 10 hours longer to produce 660 sprockets than machine B. Machine B produces 10 percent more sprockets per hour than machine G. How many sprockets per hour does machine G produces?  Choose the correct choice from the following
A) 6
B) 6.6
C) 60
D) 100
E) 110
I think the correct answer is A.   Machine G produces at a speed of G sp/hour and B at a speed of B sp/hour.   so, 660/G=(660/B)+10 and B=1,1 G---&gt;1,1*660=660+11G---&gt;6=6, so answer 6 is correct
