Problema Solution
Tom and Janet's combined income is $82,300. Janet earns $3400 more per year than Tom. How much did Tom earn per year?
Answer provided by our tutors
Let j represent Janet's income
t represent Tom's income
Janet earns $3400 more than Tom:
j = t + 3400
Together, Janet and Tom earn $82300
j+t= 82300
...substituting 'j' with its equivalent: 't+3400'
2t+3400=82300
...solve for Tom's income:
t = (82300-3400)/2 = 39450
...solve for Janet's income:
j = 82300 - 39450 = 42850
