Payments of 75 each are made every 2 months from September 1, 2006 to July 1, 2011, inclusive. For each of the following cases draw the time diagram line and find the value of the series:

(a) 2 months before the first payment at effective compound annual interest rate i = 0.05;

(b) 10 months before the first payment at nominal interest rate i(12) = 0.12 compounded monthly;

(c) 2 months after the final payment at nominal discount rate d(4) = 0.08 compounded quarterly;

(d) one year after the final payment at annual force of interest = 0.07.
