Debt

Joe and Caryl have a debt of $100,500. Joe makes $90,000 annually, and Caryl makes $35,000 annually. Based on their salaries, how much should both pay to zero out the debt fairly?

Correct answer:

c =  28140
j =  72360

Step-by-step explanation:


j+c = 100500
j = 90000/35000·c

c+j = 100500
90000c-35000j = 0

Pivot: Row 1 ↔ Row 2
90000c-35000j = 0
c+j = 100500

Row 2 - 1/90000 · Row 1 → Row 2
90000c-35000j = 0
1.39j = 100500


j = 100500/1.38888889 = 72360
c = 0+35000j/90000 = 0+35000 · 72360/90000 = 28140

c = 28140
j = 72360
