Jeanne makes hair bows to sell at the craft fair. each bow requires 1.5 yards of ribbon. if jeanne wants to make 84 bows, how many feet of ribbon must she buy

Jeanne must buy 378 feet of ribbons to make 84 bows.

Step-by-step 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.
