    Her weekly allowance is $20

    Step-by-step explanation:

    Let her weekly allowance be 'a'

    Given that,

    She spent half of the allowance (a/2)

    So,

    Money left with her = (a/2)

    She earned $6 by washing the car

    She has $16 at the end.

    So,

    (a/2) + 6 = 16

    (a/2) = 16 - 6

    (a/2) = 10

    a = 10 x 2

    a = 20

    So, her weekly allowance is $20
