Given that Ruby bought 15 cell phone cases for a total of $145.80. This means that each cell phone case costs $9.72 each. She sells each for $19.50, but only 5 out of the 15. So the total earnings she has is $97.50. Therefore, we can say that Ruby did not earn a profit but is experiencing a loss of $48.30. Hope this answers your question.
