    84 dollars

    Step-by-step explanation:

    use x to represent the amount of money Laura had when she started shopping.

    use y to represent the amount of money she had left after buying a pair of shorts.

    You can create these two equations:

    3/4x=y

    2/3x=42

    now, subsitute the value of y into the second equation.

    2/3 (3/4x) = 42

    1/2x=42

    x=84
