The complete question describes the use of word problems to represent inequalities. The $21 means that there is a limit to the number of stops she can take using the train.
The inequality that represents this scenario is:

From the complete question, we have the following parameters:
Initial Fee = $5
Rate per stop = $2.75
Amount = $21
The inequality that represents the scenario is as follows:
Initial Fee + Rate * Number of stops <= Amount
We use <= because the total charges must not exceed the amount.
Let the number of stops be x.
The above formula becomes

The answer is 168. 12% is also 0.12. 150(0.12) is 18. 150+18=168
The coordinate of the midpoint:
x m = ( x 1 + x 2 ) / 2
x 1 = - 2, x 2 = 12
x m = ( - 2 + 12 ) / 2 = 10 / 2 = 5
Answer:
The coordinate of the midpoint of a line segment PB is 5.
