    W=her allowance

    half was spent so half was left

    w/2 was left

    she earned 5 dollars

    (w/2) + 5=result

    she ended with 8 dollars

    so

    (w/2) + 5=8

    solve for w

    minus 5 both sides

    w/2=3

    multiply both sides by 2

    w=6

    her weekly alloance was $6
