Since 20 purchased fries (includes fries only and fries with hamburger)
subtract those that purchased hamburger and fries
means 3 customers only ordered fries
28 total - 3 fries only - 17 hamburger and fries
*Question is misleading. If you say hamburger or fries. Then none should have purchased both. Should have said hamburger and/or fries.*
