Aprincipal of $3800 is invested at 6.75% interest, compound annually. how much will the investment worth after 9 years?

$6840.60

Step-by-step explanation:

formula od compound interest A= P (1 =r/n)ⁿ⁹

where n=1 when it is compunded annually  and t= 9 years

A= 3800(1+6.75/100)⁹

A= 3800 ( 1+0.0675)⁹

A= 3800(1.0675)⁹

A=3800(1.800)

A= 6,840.60 $

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
