Start with

$12h+240>360$

Subtract 240 from both sides:

$12h>120$

Divide both sides by 12:

$h>10$

So, she needs to work at least 10 hours. Note that this is the minimum number of hours Ellie needs to work this week to earn at least $360 by the end of the month. This problem has no maximum: the more she works, the more she gains, so there's likely a typo in the question.
