Question

How many hours will it take to mow all of the lawns? (When is ŷ = 0?)

Short answer

The number of hours taken to mow all the lawns is 1.125

Step-by-step solution

Step 1  Given Information

Given that the total area of the properties combined is 1,345 acres.

We have to find the hours that will take to mow all of the lawns

Explanation

Consider the given equation as given below:

$\hat{y}=1350-1.2x$

When all lawns are mowed, it means that no number of acres is left to mow, that is $\hat{y}=0$. Then, the number of hours taken to mow all the lawns is:

$0=1350-1.2x$

That is 1.2x=1350

$x=\frac{1350}{1.2}$

x=1.125
