How much would $200 invested at 6% interest compounded annually be worth after 6 years? round your answer to the nearest cent. do not include units in your answer.

A= P(1 + r)^n  
where,
A= final balance 
P= initial quantity 
n= number of compounding periods 
r= percentage interest rate 
So,
P= $200 
n= 6 years 
r= 6%= 0.06 

=$200(1 + 0.06)^6 
=$283.70

Amount= 
Amount= 200(1+0.06
Amount=200
Amount=283.70

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
