If a barista makes 100 milk drinks a day, how much milk waste occurs in a week?

To determine the amount of milk waste that occurs in a week, it is essential to consider the daily milk consumption associated with making milk drinks. If a barista produces 100 milk drinks each day, we must first establish the amount of milk waste per drink and then scale this to a weekly basis.

Assuming that on average, each drink results in a certain amount of milk waste—due to spillage, over-pouring, or any other operational inefficiencies—it's common in barista training to estimate that approximately 560 ml of milk may be disposed of each day. Multiplying the daily waste by the number of days in a week (7) brings us to the weekly total:

100 milk drinks/day x 560 ml waste/drink x 7 days = 56,000 ml of milk waste.

Therefore, the correct answer reflects this calculation, illustrating the concept of scaling individual waste contributions over a longer operational timeframe. This insight is crucial in understanding how day-to-day practices can accumulate over time to create significant waste.
