Answer:
2,3,4,5 hours
Step-by-step explanation:
Now according to given data
Life guard job = $18/hr
Now she worked for 14 hours
Total earning for life guard job = $252
Remaining money to earn = 270 -252

Now she makes $10 for car washing, so if she works for at least two hours she can meet her requirements.
Now remaining hours she is allowed to work are = 19-14 = 15 hours
So she can work fro 2,3,4,5 hours to meet her requirements.
