At the beginning of every year, molly deposits $200 in a savings account that offers an interest rate of 20%, compounded annually. the total amount that molly will have in her account at the end of 3 years is $

find the sum of a finite geometric series.

a.The total amount that Molly will have in her account at the end of 3 years is $345.60

b. The sum of finite G.P series , when r<1

The sum of finite G.P series , when r>1

Step-by-step explanation:

Given

Molly deposits saving in her account= $200

Interest rate=20%

Time =3 years

Amount,A

Where P= principle value

r= Interest rate annually

t= time in years

A=Amount

P=$200

r=20%

t=3 years

Substitute all values in the given formula

A=

A=

A=

A=

A=345.6

Amount=$345.6

Hence, Molly will have total amount in her account at the end of 3 years is $345.6.

b. Let finite  G. P series

Total terms=n

Hence, common ratio=r

Sum of finite G.P series, when r>1

Sum of finite G.P series, when r<1.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
