Answer 1

your required order is
B,C,A,D

Answer 2

2 → 3 → 1 → 4

Explanation:

We are given the list of cost of fabric in dollars per square yard.

So, the total cost per square yard of different fabric are:

1. 6.5 for $6.25 =
`(6.25)/(6.5)` = 0.96

2. 4 for $3 =
`(3)/(4)` = 0.75

3. 8.5 for $8.10 =
`(8.10)/(8.5)` = 0.95

4. 6 for $7.20 =
`(7.20)/(6)` = 1.2

Since, 0.75 < 0.95 < 0.96 < 1.2

Hence, from least to the greatest unit cost, the sequence is 2 → 3 → 1 → 4.
