Introduction

The cafeteria at a local school kept track of the type of milk students chose at lunch today. The data collected includes the number of students from 7th and 8th grade who chose plain and chocolate milk. In this article, we will analyze the data and discuss the mathematical concepts involved.

Data Analysis

The data collected is presented in the following table:

Grade	Plain Milk	Chocolate Milk
7th	18	32
8th	28	22

Total Number of Students

To find the total number of students who chose milk, we need to add the number of students from each grade who chose plain and chocolate milk.

Let's denote the total number of students as T. We can calculate T as follows:

T = (Number of 7th graders who chose plain milk) + (Number of 7th graders who chose chocolate milk) + (Number of 8th graders who chose plain milk) + (Number of 8th graders who chose chocolate milk)

T = 18 + 32 + 28 + 22 T = 100

Ratio of Students Who Chose Plain Milk to Chocolate Milk

To find the ratio of students who chose plain milk to chocolate milk, we need to divide the number of students who chose plain milk by the number of students who chose chocolate milk.

Let's denote the ratio as R. We can calculate R as follows:

R = (Number of students who chose plain milk) / (Number of students who chose chocolate milk)

R = 18 / 32 R = 0.5625

Ratio of 7th Graders to 8th Graders

To find the ratio of 7th graders to 8th graders, we need to divide the number of 7th graders by the number of 8th graders.

Let's denote the ratio as S. We can calculate S as follows:

S = (Number of 7th graders) / (Number of 8th graders)

S = 18 / 28 S = 0.6429

Mathematical Concepts

The data analysis involved in this problem requires the application of several mathematical concepts, including:

Addition: To find the total number of students who chose milk.
Division: To find the ratio of students who chose plain milk to chocolate milk and the ratio of 7th graders to 8th graders.
Fractions: To represent the ratios as fractions.
Percentages: To represent the ratios as percentages.

Conclusion

In conclusion, the cafeteria data analysis problem involves the application of several mathematical concepts, including addition, division, fractions, and percentages. By analyzing the data, we can gain insights into the preferences of the students and make informed decisions about the types of milk to offer in the cafeteria.
