    Answer:

    Paul is the youngest at 17 years old. Fiona is 20 years old, Sara is 23 years old

    Step-by-step explanation:

    Assign variables to the ages.

    S = sara’s age

    F = Fiona’s age

    P = Paul’s age.

    S + F + P = 60

    S = 3 + F

    P = F – 3

    (3 + F) + F + (F – 3) = 60

    3 + 3F – 3 = 60

    3F = 60

    F = 20

    S = 23

    P = 17
