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)

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
