SOLUTION: Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$49 thousand less than twice that of an individual whose final degree is a&#820

Let x = the average yearly salary of an individual with the bachelor's degree, in dollars.


Then the average yearly salary of an individual with the master's degree is (2x-49000) dollars, according to the condition.


Next, the condition says that the sum of these salaries is 113000 dollars:


x + (2x-49000) = 113000.


Simplify and solve:


3x = 113000 + 49000 


3x = 162000   ====>  x =  = 54000.


Answer.  The average yearly salary of an individual with the bachelor's degree is 54000 dollars.


         The average yearly salary of an individual with the master's degree is 2*54000 - 49000 = 59000 dollars.
