Jina borrowed $8000 at a rate of 18%, compounded semiannually. Assuming she makes no payments, how much will she owe after 5 years?

$18,938.90

Step-by-step explanation:

The formula for compound interest is A=P(a+r/n)^n(t)

A= final amount

P= original amount

r= interest rate

n = number of times interest is compounded

t= time

so in this case your formula will look like A= 8000(1+.18/2)^2(5)

your n amount is 2 because you are compounding semi annually so twice a year and your t is 5 because you are looking for the amount after 5 years. Therefore A = 18938.9

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
