Question

Manuallu calculate the compound interest on an investment of $12,000 at 7.5% interest, compounded semiannually, for 2 years.

Answer 1

c.i=p(1+r/100)^n
use this formula

Answer 2

c.i-compound interest,p-principal,r=interest,n=time

Answer 3

How would I do the problem

Answer 4

p=12000,r=7.5,time is semiannual, so u take it as 4

12000(1+7.5/100)4=answer

Answer 5

find out and tell me

Answer 6

$51,600

Answer 7

c.i=amount -money borrowed
c.i=12000-answer=ur final answer

Answer 8

ur calculation is wrong check it again

Answer 9

its 16025.629
c.i=16025.629-12000=4025.629

Answer 10

its power 4 not muliply it with 4

Answer 11

answer is right?

Answer 12

12000((1+7.5/100)^4)-1)=4025.629

Answer 13

First compute the semi-annual interest rate
rate = (1+(.075/2))^2
annual rate = (1.0375)^2
annual rate = 1.07640625
annual rate = 7.640625%

total = 12,000 * (1.07640625)^2
total = 13,903.81

And to double check that here is a calculator:

Answer 14

Oh and the interest earned is
13,903.81 minus 12,000.00
= 1,903.81

Answer 15

no its wrong

Answer 16

i need to know the meaning semiannual
