You can write an improper fraction and mixed numbers
Given that Craig bought a treadmill for 400 dollars.
Useful life of the macine = x
Hence annual purchase cost spread over x years will be 400/x per year.
In addition, there is an annual maintenance cost of 36 dollars.
Hence Average annual cost in dollars = purchase cost per year+maintenance cost per year
= 
Hence answer for rational function is
either ![\frac{400}{x} +36[tex]Or [tex]\frac{400+36x}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B400%7D%7Bx%7D%20%2B36%5Btex%5D%3C%2Fp%3E%3Cp%3EOr%20%5Btex%5D%5Cfrac%7B400%2B36x%7D%7Bx%7D)
Multiply 1.54 by .3 to find 30 percent
.462 is 30 percent
subt this from 1.54 to find what is left.
1.08 rounded (1.078)
