4. Jerry invests $6000 at 7.5%/a, compounded annually. a) Determine the equation of the amount, A, after t years. b) Estimate the instantaneous rate of change in the value at 10 years. c) Suppose that the interest rate was compounded semi-annually instead of annually. What would the instantaneous rate of change be at 10 years? 4.
