Answer:
34 packages
25 packages
Step-by-step explanation:
He needs a pair of buns for each hamburger.
He needs 200 hamburger. That means that he needs 400 buns for his picnic.
If buns come in a package of 12, the number of packages he needs is:
400 / 12 = 33.33 packages
Because packages come in whole numbers, we have to round up.
That means he needs 34 packages.
If buns come in a package of 16, the number of packages he needs is:
400 / 16 = 25 packages
