Bag cost $59. Since the Average became $23,
$59 - $23 = $36
We can treat it as the bag's cost went down by $36 while the total cost of the books went up by $36
$23 - $20 = $3
Each book went up by $3.
Number of books
= $36 ÷ 3
= 12
$59 - $23 = $36

Thanks. Misread the question as him buying one more book instead of a bag.
