Answer:
Jose's cereal
Step-by-step explanation:
Per ounce:
Betty's cereal= 0.06 dollars (6 cents)
Jose's cereal = 0.09 dollars (9 cents)
Bob's cereal= 0.06 dollars (6 cents)
Betty's cereal and Bob's cereal cost the same amount per ounce (6 cents).
Jose's cereal costs 9 cents which is greater than 6 cents.
Jose's cereal costs the most per ounce
