Answer: I believe the answer would be 5.1 ounces...
Step-by-step explanation:
To get this answer I used a proportion and transformed pounds into ounces. 1lb=16oz
x/16= 2.55/8
Cross multiply....
8x=40.8
And simplify!
x=5.1
So for $8 you can get a pound, for $2.55 you can get 5.1 ounces (or 5 ounces if needed in whole numbers)
Hope this helps! Good luck! (:
