To find out how many ounces are in the container after 4 seconds, we need to add the additional cereal poured into the container over the 4 seconds to the initial amount of cereal.
The additional cereal poured in over 4 seconds is 2.25 ounces/second x 4 seconds = 9 ounces.
Adding this to the initial amount of cereal, the total amount of cereal in the container after 4 seconds is 11.5 ounces + 9 ounces = 20.5 ounces.
Therefore, there are 20.5 ounces in the container after 4 seconds.
