By calculation, Casey has a total of 18 baseballs.
How to determine the baseballs does he have?
From the question, we have the following parameters that can be used in our computation:
Baseball bags = 3
Number of baseball in each bag = 6
using the above as a guide, we have the following:
Baseball = Baseball bags * Number of baseball in each bag
Substitute the known values into the equation
Baseball = 3 * 6
Evaluate
Baseball = 18
Hence, the baseballs he has is 18
