Peter bought some bicycles for 4,000 he sold them for 6,200 making $50 on each of the bicycles how many bicycles were there

44 bicycles.

Step-by-step explanation:

First we find how much profit he made by subtracting 6200 by 4000. When we do this, we get 2200.

Then, we divide 2200 by 50, because he earned 50 for each bike, which gives us 44.

there were 124 bicycles. : )
