Machine A and machine B are each used to manufacture 880 sprockets. It takes machine A 10 hours longer to produce 880 sprockets than machine B. Machine B produces 10% more sprockets per hour than machine A. How many sprockets per hour does machineAproduce?  Choose the correct answer.
A) 6 B) 6.6 C) 8.8 D) 100 E) 110
time taken by B = t   time taken by A = t+10   qty produced by A = q   qty produced by B = 1.1 q   for B: t(1.1q) =880   qt=800   for A: (t+10)(q) = 880   qt+10q=880   800+10q=880   q=8   so A can produce 8/hour.   then B can produce = 8(1.1)=8.8/hour.   8.8
