Manufacturing A furniture company has two factories. During the firsts shift, Factory A made 250 chairs and 145 tables, and Factory $B$ made 300 chairs and 75 tables. During the second shift, Factory A made 275 chairs and 90 tables, and Factory $B$ made 240 chairs and 120 tables. Which factory made more chairs during the two shifts? Find your answer using matrices. (Table cannot copy)

Key Concepts

Matrix-Vector Multiplication

Matrix-vector multiplication is a specific operation where a matrix is multiplied by a vector to produce a new vector. This is especially useful for computing weighted sums, such as total production amounts, by effectively summing the contributions of different columns or rows in a single operation.

Data Aggregation Using Matrices

Aggregating data using matrices involves summing or combining rows or columns to extract meaningful summaries from detailed datasets. This technique is crucial when evaluating performance measures or comparing production outputs across different groups or time periods.

Matrix Operations

Matrix operations, including addition and multiplication, are used to combine and process data stored in matrices. These operations allow the calculation of aggregated totals or weighted sums, which is essential for comparing different data sets like production outputs from various entities.

Matrix Representation

This concept involves organizing data in a rectangular array of numbers or elements arranged in rows and columns. It is fundamental in linear algebra and is used to neatly display and manipulate multiple related data points, such as production numbers across different shifts or departments.
