compound interest formula,

A= P(1+(r/n))^(nt)

where A = Final amount

          P = principal

          r = annual rate of interest ( as a decimal)

         n = number of times interest compounded per year

         t = time in years

larrys final amount

    A =  P(1+(r/n))^(nt)

       =  350 ( 1+( 0.04/ 4)) ^(4*2)

       = 350( 1.01)^(8)

      =  $ 379 

peggys final amount

    A = P(1+(r/n))^(nt)

       =  350 ( 1+( 0.06/12) ^(12*2)

       = 350( 1.005)^(24)

      =  $ 394.51 

so peggy's final amount is greater than larry's final amount


hope you understood..please message if you have any doubts...thank you

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
