Answer:
average salary of who has bachelor degree will be $47 thousand
average salary who has master degree will be $59 thousand
Step-by-step explanation:
We have given total salary of with master degree and bachelor degree is $108 thousand
Let m for master degree and B for bachelor degree
So M+B =$108
So M = 108-B-----EQN 1
According to question M+39 =2B
M = 2B - 39-------EQN 2
From eqn 1 and eqn 2
108 - B = 2B -39
![3B=108+39=147](https://img.qammunity.org/2020/formulas/business/high-school/3ixfb8lqf0wmkki01uf254u87qoakopikn.png)
B = $49 thousand
So average salary of who has bachelor degree will be $47 thousand
From equation 1 M = 108-B = 108-49 = $59 thousand
So average salary who has master degree will be $59 thousand
