Answer:
15 years
Step-by-step explanation:
<u>Given:</u>
- Number of trees = 167
- This year limit = 4 trees
- Yearly limit following years = 6 trees per year
- Target number of trees = 50
<u>Building inequality:</u>
- 167 - 4 - 8x < 50
- 8x > 113
- x > 113/8
- x > 14.125
Adding current year to 14 we get 15 years as answer
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)
