Find the principal invested in $800 interest is earned and eight years at an interest rate of 4%

Given:

Principal: P

Interest rate: 4% (without mentioning in details, this is annual interest rate)

Interest earned: 800$

Find:

Principal

Solution:

The amount of money after 8 years with annual rate 4% is calculated by:

A = P x (1 + 4/100)^8 = 1.369 x P

A - P = 800

=> 1.369 x P - P = 800

=> 0.369 x P = 800

=> P = 800/0.369 = 2168.022$

Hope this helps!

i think the answer is b)

step-by-step explanation:

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.
