    Answer:

    Number of cookies sold is 2000 and number of cupcakes sold is 1500

    Step-by-step explanation:

    Let number of cookies be x

    and number of cupcakes be y so

    x+y=3500

    Cost of one cookie is $0.75

    Cost of one cupcake is $2

    0.75x+2y=4500

    x+y=3500 \times 2

    2x+2y=7000

    -1.25x=-2500\\\Rightarrow x=\dfrac{2500}{1.25}\\\Rightarrow x=2000

    y=3500-x=3500-2000\\\Rightarrow y=1500

    Number of cookies sold is 2000 and number of cupcakes sold is 1500.
