Answer:
The Business bought a total of 2048 pens. (I GOT THE ANSWER FROM
ChickenNugget1203)
Explanation:
The easiest way to solve this is to add the amount of bags the business bought.
7 + 9 = 16
After you find the total amount of bags bought you multiply the number of pens in each bag by the total amount of bags the business bought.
16 * 128 = 2048
