Aprincipal of $5,350 is placed in an account that earns 3.5% interest. if the interest is compounded annually, how much money will be in the account at the end of 4 years?
a.
$5,760.06
b.
$5,537.25
c.
$6,099.00
d.
$6,139.25

select the best answer from the choices provided

a
b
c
d

Option D.

Step-by-step explanation:

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  

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
