    daughter's age determines that for each year the allowance increases by 0.75

    Son's Allowance = 8.25

    Step-by-step explanation:

    The general equation is

    Allowance = Age * a base amount.

    So the six year old has givens

    Allowance = 4.50

    Age = 6

    Base amount = x

    4.50 = 6 * x Divide by 6

    4.50 / 6 = 6 x/6 Do the division

    0.75 = x

    So every year is worth 75 cents.

    Eleven year Old

    Allowance = ? = y

    Base amount = 0.75

    age = 11

    Allowance = Age * base Amount

    y = 11 * 0.75

    y = 8.25
