    The total cost of the party (C), can be expressed as;

    C=10 n+30, where n is the number of children

    Step-by-step explanation:

    Step 1

    We can use the expression below to calculate the total cost of the party as shown;

    C=F + (V*n)

    where;

    C=total cost of the party

    F=fixed cost to design party

    V=cost per child

    n=number of children at the party

    In our case;

    F=$30

    V=$10

    n=n

    replacing;

    C=30 + (10*n)

    C=30+10 n

    The total cost of the party (C), can be expressed as;

    C=10 n+30, where n is the number of children
