Mrs. Dugan plans to serve 100 barbecue sandwiches at the company picnic. How many packages of barbecue buns will she need if buns come in packages of 8? Packages of 12?

For packages of 8: She will need 13 packages

For packages of 12: She will need 9 packages

Step-by-step explanation:

Number of Barbecue sandwiches = 100 (given)

For packages of 8 we have, (100/8) = 12 (without the remainder)

We then add one extra package so that the 100 barbecue sandwiches are served.

So, for packages of 8, package of barbecue buns = 12 + 1 = 13

For packages of 12 we have, (100/12) = 8 (without the remainder)

We then add one extra package so that the 100 barbecue sandwiches are served.

So, for packages of 12, package of barbecue buns = 8 + 1 = 9
