    Answer:

    A drink costs $1.20

    Step-by-step explanation:

    Step 1:  Make a system of equations

    50.40 = 3p + 12d

    p = 10.80 + d

    Step 2:  Plug in p for the other equation

    50.40 = 3(10.80 + d) + 12d

    50.40 = 32.40 + 3d + 12d

    50.40 – 32.40 = 15d + 32.40 – 32.40

    18 / 15 = 15d / 15

    1.20 = d

    Answer:  A drink costs $1.20
