1. The problem statement, all variables and given/known data
Well this is the problem a plomer charges 80 bucks ones he arrives at your home and charges and extra 25 per hour.. Give the equation,, Kind of i dont get it is for extra credit but still i dont like it when i dont know how to do it 2. The attempt at a solution i put these but i think is wrong.. y=28[(x+1)]+80 But if i put 1hour.. plus 1 gives 2 hours so he would be chargin 2 hours just for working one.. Nice deal!! hahaha But still i dont think this is it

Hi Kino! Welcome to PF!
you just need to replace (x+1) by something else … then you can check that it's right in exactly the same way that you checked that (x+1) was wrong. (btw, what did this have to do with "greatest integer"? )
