Machine A and machine B are each used to manufacture 550 sprockets. It takes machine A 10 hours longer to produce 660 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 choice from the following answers:
A) 5.5 B) 6.6 C) 60 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) =550   qt=500   for A: (t+10)(q) =550   qt+10q=550   500+10q=550   q=5   so A can produce 5/hour.   then B can produce = 5(1.1)=5.5/hour.   5.5
