Answer:
20, 30, 40
Explanation:
You have to look at the points. You don't need to worry about the number of days. Just focus on the ounces. Look for the MOST points that align with the ounces. In this case, 20 ounces has 2 points, 30 ounces has 2 points, and 40 ounces has 2 points. 50 ounces has 1 point and 10 ounces has 0 points, so we can conclude that 50 and 10 are not our answers.
