Answer:
The number of bicycle the store sell each month is 35 .
Step-by-step explanation:
Given as :
The cost of the bicycle store to operate = x = $4200 per month
The store pay an average cost of = y = $75 per bike
The average selling price of each bicycle = s.p = $195
Let The number of bicycle sell by store each months = n
<u>Now, According to question</u>
The rest amount for each bicycle = The average selling price of each bicycle - The store pay an average cost of
I.e The rest amount of each bicycle = s.p - y
Or, The rest amount of each bicycle = $195 - $75
Or, The rest amount of each bicycle = $120
Again
The number of bicycle sell by store each months = ![\dfrac{\textrm The cost of the bicycle store to operate }{\textrm The rest amount of each bicycle }](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctextrm%20The%20cost%20of%20the%20bicycle%20store%20to%20operate%20%7D%7B%5Ctextrm%20The%20rest%20amount%20of%20each%20bicycle%20%7D)
Or, n = ![\dfrac{4200}{120}](https://tex.z-dn.net/?f=%5Cdfrac%7B4200%7D%7B120%7D)
∴ n = 35
So, The number of bicycle the store sell each month = n = 35
Hence , The number of bicycle the store sell each month is 35 . Answer
