YOU NEED TO FIND THE PRICE PER OUNCE OF EACH PRODUCT TO COMPARE THE PRICES.
489/17=28.7647 CENTS PER OUNCE
569/21=27.095 CENTS PER OUNCE
OBVIOUSLY THE 21 OUNCE PACKAGE IS CHEAPER BY ABOUT 1.7 CENTS.

----------
You need to figure out the cost per ounce for each cereal.
489/17=28.76 cents per ounce for the 17 ounce box.
569/21=27.09 cents perounce for the 19 ounce box.
----------
The 19 ounce box is the better buy.
