Answer:

doctorate salary: d = $71,000

bachelor salary: b = $55,000

Step-by-step explanation:

doctorate salary: d

bachelor salary: b

relationship between b and d: d = 2b - $39,000

Unfortunately, your "1 + 126,000" could not be correct. I'm going to assume that the total of the two salaries is $126,000. If that's the case, then:

bachelor salary + (2 times bachelor salary less $39,000) = $126,000. In symbols,

b + 2b - $39,000 = $126,000

Consolidating the 'b' terms results in 3b - $39,000 = $126,000, and so:

3b = $126,000 + $39,000 = $165,000

Dividing both sides by 3 yields the bachelor salary: b = $55,000

Then the doctoral salary is 2b - $39,000 = 2($55,000) - $39,000, or $71,000.

Check: Does b + (2b - $39,000) = $126,000? Yes.

Then the doctoral salary is d = $103,000, and the bachelor salary $29,000
