    Answer:

    C

    Step-by-step explanation:

    Here, we want to find an equation in the options which is same as the equation given in the question;

    The equation we are testing against is;

    0.05n + 0.1d = 3.65

    What we can do here is divide through by 0.01

    So we will have;

    0.05n/0.01 + 0.1d/0.01 = 3.65/0.01

    = 5n + 10d = 365
