Here is the answer to the question above. Given that Jack has 3 boxes of pencils with the same number of pencils in each box. Since he has now 28 pencils all in all because his mother gave him 4, therefore, the original number of pencils he has is 24. Since he has 3 boxes, 24 divided by 3 is 8. Therefore, each box has 8 pencils. Hope this helps.
