The recipe for a four-person cake requires 2 eggs and 4 cups of milk. Tyler wants to use this recipe to make a cake for eight people. If Tyler has 3 eggs in the fridge, how many more eggs does Tyler need to buy? Let's be accurate as possible.
User
A cake for eight people would require 8 / 4 = 2 times as many eggs as a 4 people cake. If a 4 - person cake requires 2 eggs, then an 8 - person cake requires 2 x 2 = 4 eggs. Tyler needs to buy 4 - 3 = 1 more egg.
The answer: 1.
