This is a problem related to percentage problems so in order for us to know the answer, we need to analyze the whole problem first. Given that Sasha brought 50% more candies than Erin, we can represent Erin's candies as 100% and for Sasha's as 150%. On the next part, after Erin brought 8 more candies, Sasha had 20% more. In this case, since Erin represents 100%, Sasha now as 120%. Basing on this problem, we can say that the 20% is equal to 8 candies. This would mean that Erin started with 32 candies and Sasha started with 48 candies. Hope this helps.
