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

Correct result:

c =  28140
j =  72360


j+c = 100500
j = 90000/35000•c

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

c = 28140
j = 72360
