Machine A and machine B are each used to manufacture 330 sprockets. It takes machine A 10 hours longer to produce 330 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 option.
A) 3.3	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) =330   qt=300   for A: (t+10)(q) = 330   qt+10q=330   300+10q=330   q=3   so A can produce 3/hour.   then B can produce = 3(1.1)=3.3/hour.   3.3
