Question

Ebba is buying bulk fabric. She is shopping for the best deal.

1)6.5 square yards for 6.26
2)4 square yards for 3.00
3)8.5 square yards for 8.1
4)6 square yards for 7.2
Drag the fabric in order from the least to the greatest unit cost in dollars per square yard.

Answer 1

In order to assess each of the deals equally, one has to know the price per yard of the given items.

1. 6.5 square yards for 6.26
n1 = 6.26 / 6.5 square yards
n1 = 0.963/square yard

2. 4 square yards for 3
n2 = 3/4 square yards
n2 = 0.75/square yard

3. 8.5 square yards for 8.1
n3 = 8.1/8.5 square yards
n3 = 0.953/square yards

4. 6 square yards for 7.2
n4 = 7.2/6 square yards
n4 = 1.2/square yard

From least to greatest the order would be 2,3,1, and 4.
