Answer:
3 notepads
Explanation:
Since we know that only 1 magazine was bought, we can say that he spent a total of 5$ * 1 Magazine to see he spent $5 on magazines.
Then, we subtract that from the total spent to get:
$14 - $5 = $9
Now, we divide the $9 by the $3 cost of notepads to figure out how many were bought.
9/3 = 3
So three notepads were bought
