Chapter 12, Problem 35P

Use the following information to answer the next three exercises. A landscaping company is hired to mow the grass for

several large properties. The total area of the properties combined is 1,345 acres. The rate at which one person can mow is

as follows:

   $\hat{y}\text{=135}0–\text{1}.\text{2}x$where x is the number of hours and $\hat{y}$ represents the number of acres left to mow.

35. How many hours will it take to mow all of the lawns? (When is $\hat{y}$= 0?)
