Levinsonâ€™s Hardware has a number of bikes and tricycles for sale. There are 27 seats and 60 wheels all told. Determine how many bikes and tricycles there are in the store

• math -

If there were 27 bikes, then there are 6 wheels left over. So there must be 6 tricycles and 27-6=21 bicycles.

• math -

what do you mean there are 6 wheels left over?

• math -

If there were only 27 bikes,
2*27=54
then there will be 6 wheels left.
Change each extra wheel together with a bike for a tricycle, you will get 6 tricycles and 21 bikes.
