    Amount of money raised for 875 people=A=$21,875

    Step-by-step explanation:

    This can be expression in the equation, A=k. N;

    Where;

    A=Amount of money raised=$2500

    k=Constant of proportionality (Amount of money per attendee)

    N=Number of attendees=100

    Replacing in the expression;

    Amount of money raised=K*Number of people who attend

    2500=K*100

    K = (2500/100) = 25

    Amount of money per attendee=K=$25 per attendee

    How much money was raised for 875 people?

    Using the expression, A=k. N

    where;

    Number of people (N) = 875

    k=25

    Replacing;

    A = (25*875) = $21,875

    Amount of money raised for 875 people=A=$21,875
