If the limit is 17 hours and the minimum for her to make is $250 she would need to work anywhere from 12 - 15 hours of baby siting to meet the requirements, for example if she worked 12 hours she would receive $260 ( including the $20 from babysitting ) if she worked 13 she would receive $280 ( including the $20 ) so on and so fourth, it’s pretty straight forward.
Hope this helps and I can get the brainliest
