The correct answer is 17 hours


Here’s how you solve it!

First you would want to find how much she makes per hour so divide it

252➗12= 21

She makes $21 per hour

Then divide 357 with 21 and you would get 17

To check your answer you can do 17✖️21 and you would get 357

She would have to work 17 hours to make $357


Hope this helps! :3
