Lizzy: There are four members in one household. Each member consumes 3 slices of bread during breakfast and 2 slices of bread for snacks. A loaf of bread has 12 slices. How many days will five loaves of bread last in this family?.
Me: Hmmm, let me think. I think this is the detailed solution:
A total of 3 + 2 = 5 slices of bread are consumed by each member every day. So a family consumes a total of 5 x 4 = 20 slices of bread every day. Five loaves of bread have 5 x 12 = 60 slices of bread. Thus, the 5 loaves of bread last for 60 / 20 = 3 days. Final answer: 3.
