    Let a be the cost of the fist plan

    b is the cost of the second plan

    t is the number of session

    a = 45t + 10

    b = 35t + 30

    solve when will the cost be equal

    45t + 10 = 35t + 30

    10t = 20

    t = 2

    after two session plan a will always be more expensive than plan b
