    D) 68 carnations & 32 roses

    Step-by-step explanation:

    First of all, we need to identify the parts of the problem that we already know.

    1) The events committee bought a total of 100 flowers.

    2) The events committee spent a total of $139 on the carnations and roses, combined.

    3) One carnation costs $0.75

    4) One rose costs $2.75

    We can create a formula to find the price of the flowers:

    (x times $0.75) + (y times $2.75) = $139

    If we calculate it out, the only option that fits the equation is 68 carnations and 32 roses.
