The bar graph shows average yearly earnings in the United States for people with a college education, by final degree earned. Exercises $23-24$ are based on the data displayed by the graph. (GRAPH CANNOT COPY) The average yearly salary of an American whose final degree is a master's is 49 dollars thousand less than twice that of an American whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn 116 dollars thousand. Find the average yearly salary of Americans with each of these final degrees.

Key Concepts

Systems of Linear Equations

Systems of linear equations consist of two or more linear equations that share common variables and describe multiple constraints on these variables simultaneously. In solving such systems, one finds values for the unknowns that satisfy every equation in the system, often through methods like substitution or elimination.

Word Problem Interpretation

Interpreting a word problem involves translating a real-world scenario into a set of mathematical equations. This process includes defining appropriate variables, understanding the relationships and constraints described in the text, and setting up equations that accurately represent the problem's conditions.

Substitution and Elimination Methods

The substitution and elimination methods are systematic approaches to solving systems of linear equations. Substitution involves solving one equation for one variable and then replacing that variable in another equation, while elimination involves adding or subtracting equations to remove one variable, thus reducing the system to a single equation that can be solved easily.
