Question

A bicycle store costs ​$42004200 per month to operate. The store pays an average of ​$7575 per bike. The average selling price of each bicycle is ​$195195. How many bicycles must the store sell each month to break​ even?

Answer 1

The number of bicycle the store sell each month is 35 .

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

Now, According to question

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 =
`(\textrm The cost of the bicycle store to operate )/(\textrm The rest amount of each bicycle )`

Or, n =
`(4200)/(120)`

∴ 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
