Answer:
<h2>The hourly ratio is $60 per hour, and the initial amount charged would be $30.</h2>
Step-by-step explanation:
In this problem, we just have to find the linear relation that model this situation, where the rate would be the slope, and the initial amount would be the y-axis interception. So, basically we have to find the slope-intercept form of this linear relation.
First, we finds the slope using the two given points:
Now, using one point, the slope and the point-slope form, we have:
Therefore, the hourly ratio is $60 per hour, and the initial charge would be $30.
