Answer:
The 3 feet fabric will cost $ 1.09728 almost $ 1.10 
Step-by-step explanation:
First we will find out how many meters 3 feet will be. 
1 feet = 0.3048 meters
She needs 3 feet of fabric
3 *1 feet = 3* 0.3048  ( multiplying both sides by 3)
3 feet = 0.9144 meters
Using the unitary method we will find the cost of 3 feet of fabric
1 meter costs $ 1.20 
0.9144 *1 meter costs $ 1.20 * 0.9144  ( multiplying both sides by 0.9144)
0.9144  meter = $ 1.09728 
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
