Final answer:
The ASB can make 25 smaller posters with the 50 ft roll of decorative paper.
Step-by-step explanation:
To find out how many smaller posters can be made, we need to divide the length of the roll of decorative paper by the length of each smaller poster. Let's assume that the length of each smaller poster is 2 feet. So, we can divide 50 ft by 2 ft to find the number of smaller posters that can be made:
Number of smaller posters = 50 ft / 2 ft = 25 posters
Therefore, the ASB can make 25 smaller posters with the 50 ft roll of decorative paper.
