    My working out but i have gone wrong somewhere

    Step-by-step explanation:

    Simultaneous equations

    3C+4t=6.60 x 2

    1C+8t=7.20

    6c+8t=13.20

    1c+8t=7.20 Subtract

    5 Cheese burgers=6

    1 cheese burger = 1.20

    Substitute

    1.20+8t=7.20

    8t = 6

    taco = 1.34
