We have that the price of a train ticket has an initial fee of $5 and $2.75 per stop.
Then, we can represent this using the next inequality:
In the inequality, we have some restrictions:
• Julia only has $21, no more than that.
,
• In the inequality, we need to talk about the same units. If we have units in money on one side of the inequality, we need to have the same units on the other side of the inequality.
,
•
Therefore, the scenario can be described by the inequality presented in the first option (option A).
