    Answer:

    carnation $2.50; rose $3.00

    Step-by-step explanation:

    Let c = price of 1 carnation.

    Let r = price of 1 rose.

    3c + 5r = 22.5

    3c + 2r = 13.50

    Subtract the se3cond equation from the first equation.

    3r = 9

    r = 3

    Now substitute r = 3 in the first equation and solve for c.

    3c + 5r = 22.5

    3c + 5(3) = 22.5

    3c = 7.5

    c = 2.5

    Answer: carnation $2.50; rose $3.00
