Answer:
Average yearly salaries:
Individual with master's degree: $61,000
Individual with bachelor's degree: $54,000
Explanation:
Let B be the average salary of the individual with a bachelor's degree and M be the average salary of the individual with a master's degree
We have the following equations:
M = 2B - 47000 (M is $47 thousand less than twice B)
Subtracting 2B on both sides gives
M - 2B = -47000
Dividing by -1 both sides,
-M + 2B = 47000 (1)
Combined salary is 115000
M + B = 115000 (2)
Adding equations (1) and (2) will eliminate M:
-M + 2B +M +B = 47000+115000
3B = 162000
Dividing by 3 on both sides,
B = 162000/3 = 54000
Using equation (2) we get M+54000=162000
M = 162000-54000 = 61000
We can verify these numbers are right by plugging these values into the first equation
Plugging B = 54000 into M = 2B - 47000 --> M = 2 x 54000 - 47000 -->
M = 108000-47000 = 61000
These are consistent with our computed values
Individual with master's degree has average salary $61,000
Individual with bachelor's degree has average salary $54,000
