Because you need to find the LCM (Least Common Multiple) which is the smallest number that each number can be divided into. That number would be 48, which is 3 boxes of pencils (16*3) and 8 packages of notebooks (6*8)
Part B) $34 would be how much you'll pay after the sale
Here's the math:
You have 3 boxes of pencils costing $3 each, but you'll have one for free because of the buy one get on free sale, so that's $6 you owe so far.
Next, you have 8 packages of notebooks worth $7 each. This time you only have to pay for 4 of them since you get a free one for every package you buy.
So, 4 packages at $7 each is a total of $28.
Now, we add the two totals ($6 and $28) and we get our $34
