The answer is option A:
We know that Samantha needs to earn enough money to pay for the plane ticket, which is $575. She already has $135 saved up, so the total amount she needs to earn is:
$575 - $135 = $440
We also know that she earns $15 an hour, so we can set up the inequality:
15h + 135 ≤ 575
This inequality says that if Samantha works h hours at a rate of $15 an hour, and adds her savings of $135, the total amount she earns will be less than or equal to $575, which is the cost of the plane ticket.
Therefore, Samantha can work any number of hours, as long as the inequality 15h + 135 ≤ 575 is true.
