To find out how many hours Kylie needs to work to earn $357, you need to first find out how much she earns in one hour. Since she made $68 for 4 hours of work, to find out how much she earns in one hour, take $68 and divide that amount by 4 and when you do that you get $17 for one hour of work.  To find the number of hours she needs to work to earn $357, take $357 and divide it by how much she earns in one hour which is $17 and when you do that you get 21 hours.  It will take 21 hours for Kylie to earn $357.
