Hello kayy This seems somewhat similar to the other question.

OpenStudy (anonymous):

I know i know i can bearly think right now its 2 in the morning can you please help me so i can go to bed

OpenStudy (anonymous):

you there @wolf1728

OpenStudy (wolf1728):

61,874 3.5% decline per year in 15 years = ?? So "growth" is .965 After 1 year = where y = 1 61,874 * .965^y = 59,708 After 15 years, 61,874 * .965^15 = 61,874 * 0.5860163055 36,259 I hope it's right

describe the relationship between compound interest and exponential growth

OpenStudy (wolf1728):

Wow I thought that was it I'd say they are the same thing

OpenStudy (anonymous):

how ? i have to explain ?

OpenStudy (wolf1728):

Exponential growth is increasing an amount by a specific factor. Example If we have a bacteria colony of 50 that doubles every hour after 1 hour we have 2*50 = 100 after 2 hours 2*2*50 = 200 after 3 hours 2*2*2*50 = 400 Each time the amount increases by a factor of 2 Now for compound interest

OpenStudy (anonymous):

Thank you and when you say now for compound interest do you have more ?

OpenStudy (wolf1728):

Yes The compound interest formula Total = Principal × ( 1 + Rate )^years and more if you want it

OpenStudy (anonymous):

Thank you soooo much. I do need a little more help on more questions, ill let you help others then come back to me pleasee and fast.

OpenStudy (wolf1728):

Okay for compound interest let's say annual interest rate is 5% so every year the amount increases by 1.05

describe how the account balance of a savings account earning simple interest is determined

OpenStudy (wolf1728):

Wow I wasted a lot of time on that one and still DON'T have an answer :-(

OpenStudy (wolf1728):

Simple Interest - I can do that

OpenStudy (anonymous):

OpenStudy (wolf1728):

Simple Interest is calculated on the principal and never takes the interest into account At 5% simple interest $100 0 years $105 2 years $110 3 years $115 4 years $120 5 years
