We are given
For Downtown Deli:
The size of a pickle bucket is 640 ounces
so, total ounces =640
the price is only $32
so, total price =32
now, we can find price for each ounces
Price for each ounce = (total price)/(total ounces)
Price for each ounce is
$ / ounce
and we are given
The purchasing Brand D pickles at $0.20 per ounce
So, local grocery rate is cheaper
so, Darryl should accept special offer from the local grocery store on gourmet pickle buckets........Answer
