ReplyDeletethe better buy would be the 8 pound box of Crispy Crackers. And I got that using unit rate and rounding off to the nearest tenths

The 8 ounce box is the better buy because it costs the less per ounce. I did this by doing cross products to find the unit price for each ounce. Btw I like your setup of Tang.
