You have to go through your x-axis and up or down you y-axis and then determine if the end point are on the right plot form
Let
x----------> charge per hour to rent a jet sky in dollars
y----------> the total cost to rent a jet sky in dollars
we know that
<u>First Jet Sky Company</u>
---------> equation ![1](https://tex.z-dn.net/?f=1)
<u>Second Jet Sky Company</u>
---------> equation ![2](https://tex.z-dn.net/?f=2)
we know that
To find the number of hours for which the costs are the same
equate equation
and equation ![2](https://tex.z-dn.net/?f=2)
The intersection both graphs is the solution of the problem
using a graph tool
see the attached figure
the intersection point is ![(4,33)](https://tex.z-dn.net/?f=%284%2C33%29)
That means
For ![x=4\ hours](https://tex.z-dn.net/?f=x%3D4%5C%20hours)
the cost of the rent is
in both companies
therefore
<u>the answer is</u>
![4\ hours](https://tex.z-dn.net/?f=4%5C%20hours)
