Answer:
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
