    16 state quarters and 7 new $1 coins.

    Step-by-step explanation:

    A child is collecting state quarters and new $1 coins.

    She has a total of 23 coins.

    The number of quarters is 9 more than the number of dollar coins.

    Let the number of dollar coins be x.

    The number of quarters will be x + 9

    x + (x + 9) = 23

    2x + 9 = 23

    2x = 23 - 9 = 14

    2x = 14, x = 7

    So the child has 7 new dollar coins and 7 + 9 = 16 state quarters.
