Ellen Obrien earns $24.68 per hour as an aircraft mechanic at a local airport. How many hours per week must she work if she wants to earn approximately $850 per week?

34.45 However it would be 35 hours if you are not able to enter decimals.

Step-by-step explanation:

What you have to do to get this answer is times 24.68 by a decent variety in numbers to find the answer. However it needs to be realistic, such as at least less then 168. Considering in a week if you are at your job 24/7 all week long you would spend 168 hours in there. And honestly no one would really be able to considering if she wants to earn 850 per week she would not be able to get ready, basic needs, or do anything else in her life such as eating. However you find the answer is 34.45 hours since when you do 24.68 x 34.45 hours you get $850.226 per week. You can get more specific then $850.226 however generally $850.226 per week would be better then just to get $850 per week.

You also can't just do 34 hours per week as you would earn less then the goal you have set to earn every week. However you can do 35 hours per week although it would give you a few dollars more then the goal that is aimed for. However if you want to get more specific then that you get 34.45 hours per week and you earn $850.226

Hope this helps! Also if you need any further help with this question just let me know.
