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.
