Answer:
Jeanne must buy 378 feet of ribbons to make 84 bows.
Explanation:
Given:
Each bow required = 1.5 yards of ribbon
Number of bow to make = 84
We need to find the length of ribbon in feet to make 84 bows.
Solution:
First we will find length of ribbons in yards required to make 84 bows .
Now we know that;
1 bow =1.5 yards of ribbons
84 bows = length of ribbons in yards
By using Unitary method we get;
length of ribbons in yards =
Now we know that;
1 yard = 3 feet
126 yard = length of ribbons in feet
Again by using Unitary method we get;
length of ribbons in feet to make 84 bows =
Hence, Jeanne must buy 378 feet of ribbons to make 84 bows.
