Hector and Francis spent a total of $47.50 at the mall. If Hector spent 50% more than Francis, how much did Francis spend at the mall?

Let Francis’s spending be x dollars. Hector spent 50% more, so he spent 1.5x; together they spent x + 1.5x = 2.5x = $47.50. Dividing $47.50 by 2.5 gives x = $19.00, so Francis spent $19.00.
