    Step-by-step explanation:

    Plan A: A = 20G

    Plan B: B = 15G + 40

    To see when they will be equal set the equations equal to each other

    20G = 15G + 40

    5G = 40

    G = 8

    At 8 GB they will cost the same amount.

    20(8) = $160

    15(8)+40 = $160

    Hope it will be Helpfull

    thank you
