Virginia, Adrienne, and Dennis have taught history for a combined total of 96 years. If Virginia has taught for 9 more years than Adrienne and for 9 fewer years than Dennis, for how many years has Dennis taught?
Why am I wrong in my setup?
V= A + 9
D= V + 9= ( A + 9) + 9
D= A + 18
Nothing. Now that you have V, A, and D all in terms of A, is there a relationship among V, A, and D that you can use?
