Adealer bought some bicycles for $4,000 he sold them for $6,200 making $50 on each bicycle. how many bicycles were there?

In this question, we're trying to find how many bikes were there.

We know that they bought them for $4,000

We also know that they sold them for $6,200

Lets find how much profit they made:

Subtract 6200 by 4000 to find how much profit was made

6200 - 4000 = 2200

The dealer made $2,200 in profit

Now, since we know that they made $50 from each bike, we would divide 2200 by 50 to get our answer.

2200 ÷ 50 = 44

This means that there were 44 bicycles.

44 bicycles

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
