    The rate of change in price is

    $0.2 per year

    Step-by-step explanation:

    This problem bothers on rates

    Given data

    Initial price of milk = $2.7

    Final price of milk = $3. 5

    Time duration = 4 years

    Hence the rate of the change of price can be estimated as follows

    = Δ in price/Δin time

    = (Final price - initial price) / 4

    =3.5-2.7/4

    =0.8/4

    =$0.2 per year
