Please answer all parts and show your work. If you do both, I will give a rating.

Hopefully this helps clarify the symbols.

3.4 You are given the following information: i = 2.1%, i5 = 2.6%, i = 3.1% and i1 = 3.6%. (a) Calculate the rates of interest if, i, i and ia. (b) Calculate z and 59. Note that the first payment is made at time 0, and the last payment is made at time n 1. We denote the present value of the annuity-due at time 0 by i (or n if the rate of interest i per payment period is understood), and the future value of the annuity at time n by mli (or n if the rate of interest i per payment period is understood). The formula for can be derived as follows n 1+0+ ... + 0-1 1 un 1 - 0 un 1 = (2.3) d Also, we have 5 n x (1 + i)" (1+i) 1 d (2.4) 3.4 You are given the following information: i = 2.1%, i5 = 2.6%, i = 3.1% and i1 = 3.6%.
