Pls help I need it again

A = $5,561

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested instead of paying it out. When it happens interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

Where:

A=final amount

P=initial principal balance

r=interest rate

n=number of times interest applied per time period

t=number of time periods elapsed

-----------------------------------

The investment is given as P=$500 at a compound interest of r=12.8%=0.128. Since the compounding period is not given, we assume n=1 (once per year). We are required to calculate the money in the account after t=20 years.

Substituting:

A = $5,561

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.
