At an effective annual interest rate of i > 0, each of the following two sets of payments has present value k: (i) a payment of 169 immediately and another payment of 169 at the end of two years. (ii) a payment of 225 at the end of two years and another payment of 225 at the end of four years. calculate k.

The present value of K is,

Step-by-step explanation:

Hi

First of all, we need to construct an equation system, so

Then we equalize both of them so we can find

To solve it we can multiply to obtain , then we have .

This leads to a third-grade polynomial , after computing this expression, we find only one real root .

Finally, we replace it in (1) or (2), let's do it in (1)

1. 34

2. 268

3. x=14.4
