Part 1) Option B.

Part 2) Option C.

Part 3) Option A.  

Part 4) Option D. About

Step-by-step explanation:

Part 1) we know that

The compound interest formula is equal to  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

substitute in the formula above  

Find the interest

Part 2) we know that

The simple interest formula is equal to

where

I is the interest amount  

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

substitute in the formula above

Part 3) we know that    

The compound interest formula is equal to  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

substitute in the formula above  

Part 4)

The account with compound interest earn about

The account with simple interest earn about

see the attached figure

The difference is equal to

therefore

the answer is about
