Introduction

Have you ever wondered how many cups are used in a coffee shop on a given day? In this article, we will delve into the world of mathematics and explore how we can use data to estimate the number of cups used on a specific day. We will examine a record-keeping system from a coffee shop and use mathematical techniques to determine the number of cups used on Thursday.

The Data

The coffee shop receives deliveries of 2,000 paper cups at a time. The record-keeping system provides us with the following information:

Day	Change
Monday	-1,500
Tuesday	-1,200
Wednesday	-1,000
Thursday	?
Friday	-800

The Problem

We are asked to estimate the number of cups used on Thursday. To do this, we need to analyze the data and identify any patterns or trends. Let's start by examining the changes in the number of cups used each day.

Analyzing the Data

Looking at the data, we can see that the number of cups used each day is decreasing. On Monday, 1,500 cups were used, on Tuesday, 1,200 cups were used, and on Wednesday, 1,000 cups were used. This suggests that the number of cups used each day is decreasing by a constant amount.

Calculating the Decrease

Let's calculate the decrease in the number of cups used each day:

Monday to Tuesday: 1,500 - 1,200 = 300 cups
Tuesday to Wednesday: 1,200 - 1,000 = 200 cups
Wednesday to Thursday: ? (we need to estimate this)

We can see that the decrease in the number of cups used each day is decreasing by 100 cups each day (300 - 200 = 100). This suggests that the number of cups used on Thursday will be 100 cups less than the number of cups used on Wednesday.

Estimating the Number of Cups Used on Thursday

Based on the data, we can estimate the number of cups used on Thursday as follows:

Wednesday: 1,000 cups
Thursday: 1,000 - 100 = 900 cups

Therefore, we estimate that 900 cups were used on Thursday.

Conclusion

In this article, we used mathematical techniques to estimate the number of cups used on Thursday at a coffee shop. By analyzing the data and identifying patterns and trends, we were able to calculate the decrease in the number of cups used each day and estimate the number of cups used on Thursday. This demonstrates the power of mathematics in real-world applications and shows how mathematical techniques can be used to solve practical problems.
