20.5 ounces

Step-by-step explanation:

Additional cereal is poured into the container at a rate of 2.25 ounces per second. t means that after each second 2.25 ounces of cereal will be added in container.

Then after 4 seconds ounces of cereal will be added in container.

After 4 seconds in container are ounces of cereal.

20.5 ounces

Step-by-step explanation:

Ounces is a measure of volume, and sometimes mass. Initially, there was 11.5 ounces in the container. Adding cereal at the rate of 2.25 ounces per second implies that 2.25 ounces were added every second.

So for 4 seconds, total ounces in the container = initial value of ounces + value of ounces added for 4 seconds

value of ounces added in 4 seconds = 4× 2.25 ounces

                                                             = 9 ounces

∴ total ounces in the container = 11.5 + 9

                                                    = 20.5 ounces
