Question

I will give brainiest to whoever answers correctly !!

Answer 1

Step-by-step explanation:

A) In order to calculate the interest , we can use the following formula :

$P=P_{0}.(1+i)^{t}$

Where P is the interest , P0 is the initial value, i is the interest and t is the time.

So , using P0 =600,i= 0.0005768 and t=27 ,we have :

$P=600.(1+0.0005768)^{27} \\P=600.(1.01569)\\P=609.41$

Calculating only the interest, we have :

$I=609.41-600\\I=9.41$

So the interest is $9.41.

B) He paid the final value calculated above, that is , $609.41.
