    C) 18 cents

    Step-by-step explanation:

    Given,

    This weeks deal -

    Quantity of Flour Price ($) Price per pound ($)

    3 pounds 5.25 (5.25/3) = 1.75

    5 pounds 9.75 (9.75/3) = 1.95

    7 pounds 12.60 (12.60/3) = 1.80

    10 pounds 14.20 (14.20/3) = 1.42

    12 pounds 18.24 (18.24/3) = 1.52

    The lowest price per pound is $1.42. Therefore, this is the current week's best deal.

    The last week's best deal was = $'1.60/pound

    The difference between the unit price for previous week's best deal and this week's best deal = $1.60 - $1.42 = $0.18

    Therefore, 18 cents.
