A shop sells bicycles and tricycles. In total there are 9 cycles (cycles include both bicycles and tricycles) and 19 wheels. Determine how many of each there are, if a bicycle has two wheels and a tricycle has three wheels.
Answers.
A) b=8,t=1
B) b=5,t=3
C) b=6,t=2
D) b=2,t=5
E) b=3,t=4
Let b be the number of bicycles and let t be the number of tricycles.   Set up the equations   b+t=9...........(1)   2b+3t=19............(2)   Rearrange equation (1) and substitute into equation (2)   2b+27-3b=19   -b=-8   b=8   Calculate the number of tricycles t   t=9−b   =9−8   =1   There are 1 tricycles and 8 bicycles.   b=8,t=1nswer is b=8,t=1.
