Answer 1

Answer:

Rate = 5%

Step-by-step explanation:

Compound interest i.e   A = P $(1+r)^{t}$

Given;

        A  =  2315.25

        P  =  2000

         t  =   3 years

         r  =  ?

Now, substitute the values

         2315.25  =  2000 $(1+r)^{3}$

            1.1576  =  $(1+r)^{3}$

                1.05  =  (1 + r)

               0.05  =  r

                  5%  =  r

There is one more term (n = number of times interest applied per time period)  in the compound interest formula which I didn't use as it was not given and not required.
