My question is: Lisa has 18 more dresses than Ana. If the number of their dresses combined is 48, how many dresses does Ana have? Your thoughts:
If Lisa's surplus of 18 dresses is taken away from the total, they will have 48 - 18 = 30 dresses in total. They would each have the same number of dresses from these 30 i.e. 30 / 2 = 15 dresses which is the number of dresses that Ana actually has. The final answer: 15.
