1. The problem statement, all variables and given/known data You have a bank account with Y amount of dollars. The interest on it is 5% a year. Every year, you extract 3,350 dollars to pay for college tuition. What is the smallest amount Y can be to allow you to pay for 4 years of college? (Use Calculus Methods) 2. Relevant equations General Differential Equation stuff. 3. The attempt at a solution Now, I believe an appropriate Differential Equation for this problem would be... dy/dt = 0.05y - 3,350 t will be 4 and y will be 0, ultimately. In class today, we got to the point where you divide both numbers by 0.05 so you get... dy/dt = y - 67000 Or something. Now we don't know where to go. Help?
