    A, B, C

    Step-by-step explanation:

    When we look at her work, which you write in comment we can see that she make mistake. So lets answer your questions.

    A) Because we cannot have 8.25 prints, we can just have integer 8 or 9. or some other integer.

    B) explain Madeline mistake:

    2 (30-p) + 5p=93 in this she needs to multiply 2 by 30 and 2 by - p, which she didnt.

    C) When we correct mistake we can evaluate how much Chris sell.

    60-2p+5p=93

    3p=33

    p=11

    s=30-p=19

    So, Chris sells prints 11 and sketches 19
