    Grayson: 35h + 35 = y
    Ian: 45h + 15 = y

    (Substituting first hour in h)
    35h + 35 = y
    35(1) + 35
    y = 70$ in the first hour for Grayson

    45h + 15 = y
    45(1) + 15
    y = 60$ in the first hour for Ian

    Grayson charges > Ian charges

    (Substituting second hour in h)
    35h + 35 = h
    35(2) + 35
    105$ in the second hour for Grayson

    45h + 15 = h
    45(2) + 15
    135$ in the second hour for Ian

    Grayson charges < Ian charges

    Answer:
    In the first hour Grayson charges more than Ian.
