    Step-by-step explanation:

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

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

    A=20,000

    r=12.7%=0.127

    t=15

    n=12

    P=?

    P=20,000 / (1+/0.127/12) ^12.7*15

    =20,000 / (1+0.0106) ^190.5

    =20,000 / (1.0106) ^190.5

    =20,000/7.4534

    P=2,683.3391

    Approximately

    P=2,683.34
