    B and E

    Step-by-step explanation:

    In the function f (m) = - 50m+300

    -50 is the gradient meaning it is the rate of change per month. This means that the rate of change is - 50 since this is the coefficient of m.

    Also, - 50m must be negative since m represents a month and you cant have negative months, so you know that the amount of money is decreasing
