Billy's family likes to keep their bicycles stored in the garage when they're not being used.  They own a total of 4 bicycles.  Each bicycle wheel has 10 spokes.  How many spokes are inside the garage?
Each bicycle has 2 wheels, so there are a total of 4*2=<<4*2=8>>8 wheels in the garage as there are 4 bicycles.
Since each wheel has 10 spokes, this means there are 8*10=<<8*10=80>>80 spokes in total.
