Think this is right
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the total cost of hiring for x hours. Hence:
- Using the points (0, 125) and (15, 950)
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour

The best measure of center tendency for this set of data would be the median. It is the best measurement because the data set has an outlier. The outlier is the 30. So to find the median we first order the data set and then find out if the set is an even or odd set. This set is even so we just chose the middle number. If the set was even, we would add the two center number and divide them by 2.
3, 3, 4, 4, 4, 5, 5, 5, 30
The center tendency = 4
I'm not good at math i cant help
