计算每次使用的价格

Question

How would you work out the price per use of an item - in my case an exercise bike -

A) Total cost / number of uses

or

B) Total cost halved per use

and how would this be done in code (Javascript specifically google sheet scripting) Right now none of my code is even beginning to come close to the two potential answers Right now its 6 uses (value automatically changes in H1 of my spreadsheet) and cost of $40 Currently i think it should be done the way B says and this is my attempt but its not giving me the expected output and i have tried a few other methods however the division within the for loop doesn't seem to get repeated even when i have only had one line.

I have removed many of the var definitions just to make the post cleaner

newppr = new price per ride

ppr = price per ride

oldppr - old price per ride

pob = price of bike

var numofRides = SpreadsheetApp.getActiveSheet().getRange('H1').getValue(); //gets number of rides from cell H1
for (i = 0; i <= numofRides; i++) {
  oldppr = pob / 2; 
  newppr = oldppr / 2;
  newppr = newppr / 2;
  ppr = newppr;
}
SpreadsheetApp.getActiveSheet().getRange('F3').setValue(newppr);   //sets new value to cell F3 
}

Am i making this over complicated and which should it be - if its A then its an easy fix but i have some doubt about which one it is any help will be gratefully received

Answer 1

Total cost/number of uses" also generates a flat rate/use but it requires an estimate of the total number of uses. Say your bike could survive 1000 uses, then $40/1000 = $0.04cents per use, and that would be a pricing policy that might apply to commodity-type products"

Thanks to Tedinoz for the response, this is the exact information I couldn't find and thank you for your time

Just for a bit of clarification, Its a bike I already have and want to justify the price of due to financial reasons alongside some nice stats on my personal tracking spreadsheet. Your final comment is the best it's just instead of the $40 / 1000 it will be my current number of uses so there is no need for code to attempt to half the cost for each use! Turns out I was really overthinking this and it is just a simple cell / cell. Many many thanks.
