Answer:
B. 120
Step-by-step explanation:
Each ribbon is 25 yards long. Each yard is 36 inches, so the length of the ribbon is ...
(25 yd)(36 in/yd) = 900 in
This can be divided into n pieces, where n satisfies ...
22n ≤ 900
n ≤ 900/22 = 40 20/22
That is, Erika can cut 40 22-inch pieces from each 25-yard piece, and will have 20 inches left over.
From the 3 25-yard pieces, Erica can cut 3×40 = 120 pieces of ribbon that are 22 inches long.
_____
She will have 3 pieces that are 20 inches left over.
