Amber is baking cakes for her party. She has invited 8 friends and each one will want two slices of cake. Each cake makes 6 slices. If she bakes 4 cakes, how many slices will be left over at the end if she eats three herself? Let's be accurate as possible.
Her friends will eat 16 slices of cake because 8 x 2 = 16. There will be 19 slices eaten in total because 16 + 3 = 19. She is making 24 slices of cake because 4 x 6 = 24. There will be 5 pieces left over because 24 - 19 = 5.
The answer: 5.
