5. Consider a savings account with an interest rate of a = 0.1 and an initial investment of
y (0) $100. At t = 5, a one-time deposit of $50 is made. Set up and solve an initial
value problem for the dollar value y(t) of the account. Sketch the graph of the solution.
6. With the same interest rate of a = 0.1, assume that a constant withdrawal rate of $10
per unit of time is made, starting at t = 5. Set up an initial value problem and find
the general solution u(t) (leaving the initial deposit u(0) as a free parameter). Does this
