Machine P and Machine Q are each used to manufacture 110 sprockets. It takes Machine P 10 hours longer to produce 110 sprockets than Machine Q. Machine Q produces 10% more sprockets per hour than Machine A. How many sprockets per hour does Machine A produce?	Pick one.
A) 5
B) 15
C) 55
D) 95
E) 1
P makes x sprockets per hour.   Then Q makes 1.1x sprockets per hour.   10/x = 110/1.1x + 10   1.1(110) = 110 + 11x   11x = 11   x = 1   The answer is 1
